Water Purity Detection In Real Time

May 23, 2009

A water purity detection device has been created by the lab of Prof. Abraham Katzir of Tel Aviv University’s School of Physics and Astronomy. It can detect poisons and contaminants invisible to the naked eye immediately, rather than through sampling and testing.

Modifying special fibers developed in his Tel Aviv University lab, Prof. Katzir can detect “colors” in the infrared spectrum which distinguish between pure and contaminated water. Not visible to the naked eye, this spectrum is normally only seen by certain animals, like snakes or vampire bats, to track down prey. Connected to a commercial infrared spectrometer, the fibers serve as sensors that can detect and notify authorities immediately if a contaminant has entered a water reservoir, system, building or pipeline.

In the lab, the fiberoptic system detected poisons such as pesticides in amounts well below the World Health Organization safety threshold. Preliminary field experiments have already been done at several European sites, and the results were reported recently in the Journal of Applied Spectroscopy.

This will remind Dune fans of the poison snooper used by all noble-born persons on a regular basis. Pictured below is a hand-held version from a 1984 movie version; the quote below is from Frank Herbert’s 1965 novel.

Poison snoopers were installed over banquet tables for the sake of the guest’s piece of mind:

The Duke said: “Paul, I’m doing a hateful thing, but I must.” He stood beside the portable poison snooper that had been brought into the conference room for their breakfast. The thing’s sensor arms hung limply over the table, reminding Paul of some weird insect newly dead.

Fibers can defend against water terrorism (FROM MONEY TIMES)

May 20, 2009

 Home

Tel Aviv — Israeli scientists say they have developed a technology that can monitor the safety of a building’s or community’s water supplies to detect chemoterrorism.Tel Aviv University physics Professor Abraham Katzir says most Americans take the safety of their drinking water for granted, but he said ordinary tap water could become deadly within minutes.

To defend against contamination, as well as pollution caused by industrial spillage, natural disaster or sabotage, Katzir and his team created special fibers that can detect “colors” in the infrared spectrum that distinguish between pure and contaminated water.

The researchers said their fiber optic system could become one of the first real-time water monitors in the United States to provide protection from chemoterrorism attacks.

“It’s unlikely that someone will poison the water supply in Afghanistan,” Katzir said, “but America is in grave danger and needs to arm itself against chemical threats to its drinking water.”

Preliminary field experiments have been conducted at several European sites, and the results were reported recently in the Journal of Applied Spectroscopy.

TAU physicist’s ‘infrared fibers’ can defend water supplies from

A Tel Aviv University physicist has developed a system to monitor the safety of a building’s or community’s water supply in real time, which could combat the threat of contamination due to industrial spillage, natural disaster or sabotage.

Although most people take the safety of their drinking water for granted, ordinary tap water could become deadly within minutes, says Prof. Abraham Katzir of Tel Aviv University’s School of Physics and Astronomy.

Connected to a commercial infrared spectrometer, the fibers serve as sensors that can detect and notify authorities immediately if a contaminant has entered a water reservoir, system, building or pipeline.

In the lab, the fiberoptic system detected poisons, such as pesticides, in amounts well below the World Health Organization safety threshold. Preliminary field experiments have already been done at several European sites, and the results were reported recently in the Journal of Applied Spectroscopy.

Once in use, the sensor system would be one of the first real-time water monitors to provide protection from chemoterrorism attacks – a threat to which water supplies in places like the US are particularly susceptible.

“It’s unlikely that someone will poison the water supply in Afghanistan,” says Katzir, “but America is in grave danger and needs to arm itself against chemical threats to its drinking water.

With our naked eyes we can’t distinguish between pure water and water that contains a small amount of alcohol or acetone. They’re all clear. We can’t do it even with a spectrophotometer, which measures visible colors,” explains Katzir.

“But we can clearly distinguish between liquids using an infrared spectrometer which can distinguish between ‘colors’ in the invisible infrared spectrum.”

The special fiber sensors make it possible to monitor the quality of water in a remote location, such as a lake, a river, or a pipeline, and detect trace amounts of contaminants in real time, adds Katzir.

Water management executives in Florida’s Everglades and officials in Germany are among those who have expressed an interest in using the technology.

“Toxic materials are readily available as pesticides or herbicides in the agriculture industry, and can be harmful if consumed even in concentrations as low as few parts per million,” says Katzir.

Cities like New York are especially susceptible to a chemoterrorist threat. With many skyscrapers holding water reserves on the top of the building, a terrorist only needs to introduce poison into a tank to wreak havoc.

“A terrorist wouldn’t have to kill tens of thousands of people. Only 50 deaths – as horrible as that would be – would cause nationwide panic,” Katzir says.

Currently, water authorities in America test water reservoirs usually once every day or two, with no system in place to detect chemical threats instantaneously.

“This new system can cut millions of dollars from the cost of testing water manually,” he says,

The fiber sensors developed by Katzir are made of insoluble, non-toxic, and biocompatible materials.

“You can eat them and nothing will happen to you,” he notes.

Katzir’s determination to fight terrorism through science has a personal side as well. His father, world-renowned scientist Prof. Aharon Katzir, was assassinated by the Japanese Red Army in a terror attack in 1972.

“I am trying to walk in his footsteps by doing applied research that can be a practical tool in an important battle,” he says. “This system can be ready for use in less than a year.”

New system to monitor safety of building’s drinking water supply – Yahoo India

May 19, 2009

Wed, May 13 09:57 AM
New York, May 13 (IANS) Chemo-terrorists could turn drinking water into a deadly brew within minutes. To counter this, a researcher has developed a system to monitor the safety of the water supply to a building or a community.

The terrorist only needs to inject poison into a tank atop a skyscraper in cities like New York to wreak havoc, said Abraham Katzir, professor at Tel Aviv University (TAU) School of Physics and Astronomy.

‘A terrorist wouldn’t have to kill tens of thousands of people. Only 50 deaths – as horrible as that would be – would cause nationwide panic,’ he added.

Besides, ‘toxic materials, available as pesticides or herbicides, can be harmful if consumed even in concentrations as low as few parts per million’, said Katzir.

Concerned about these possibilities, Katzir developed a new system to monitor the safety of a building or community’s water supply in real time, which could be contaminated by industrial spillage, natural disaster or plain sabotage.

Currently, authorities in America test water reservoirs usually once every day or two, with no system in place to detect chemical threats instantaneously.

‘This new system can cut millions of dollars from the cost of testing water manually,’ said Katzir. His fibre sensors are made of insoluble, non-toxic, and biocompatible materials. ‘You can eat them and nothing will happen to you,’ he noted.

Modifying special fibres developed in his TAU lab, Katzir can detect ‘colours’ in the infrared spectrum which distinguish between pure and contaminated water.

Not visible to the naked eye, this spectrum is normally only seen by certain animals, like snakes or vampire bats, to track down prey.

Connected to a commercial infrared spectrometer, the fibres serve as sensors that can detect and notify authorities immediately if a contaminant has entered a water reservoir, system, building or pipeline.

In the lab, the fibre-optic system detected poisons such as pesticides in amounts well below the WHO safety threshold. Preliminary field experiments have already been done at several European sites, said a TAU release.

Once in use, the sensor system would be one of the first real-time water monitors in the United States to provide protection from chemo-terrorism attacks – a threat to which US water supplies are particularly susceptible.

‘It’s unlikely that someone will poison the water supply in Afghanistan,’ said Katzir, ‘but America is in grave danger and needs to arm itself against chemical threats to its drinking water.’

His paper was published in the Journal of Applied Spectroscopy recently.

Israeli Scientist Uses ‘Snake Vision’ to Monitor Water Purity

May 19, 2009

by Zalman Nelson

(IsraelNN.com) Prof. Abraham Katzir of Tel Aviv University’s School of Physics and Astronomy has developed a new system modeled after the biology of snakes to monitor the public water supply for poisons and contaminants in real time.
The successful results of preliminary field experiments performed at several European sites were recently reported in the Journal of Applied Spectroscopy.

Using fibers modified in his lab, Katzir found that he could detect “colors” in the infrared spectrum which distinguish between pure and contaminated water. His invention connects the fibers to a commercial infrared spectrometer that detects and notifies authorities immediately if a contaminant has entered a water reservoir, system, building or pipeline.

The infrared spectrum, not visible to human eyes, is typically used by animals like snakes and bats to track down prey.

“With our naked eyes we can’t distinguish between pure water and water that contains a small amount of alcohol or acetone. They’re all clear. But we can clearly distinguish between liquids using an infrared spectrometer which can identify ‘colors’ in the invisible infrared spectrum,” he added.

According to Katzir, ordinary tap water can become contaminated and deadly within minutes due to industrial spillage, natural disaster or sabotage. He said that his system could detect poisons like pesticides in amounts well below the World Health Organization safety threshold. “Seeing” water like a snake does, could be the first real-time water monitor to provide protection against a chemical terror attack.

“It’s unlikely that someone will poison the water supply in Afghanistan, but America is in grave danger, and needs to arm itself against chemical threats to its drinking water,” said Katzir. “Toxic materials are readily available as pesticides or herbicides in the agriculture industry, and can be harmful if consumed even in concentrations as low as few parts per million.”
