New device detects dangerous materials in water

"The tool is based on polymethacrylate sensors -- transparent portions of plastic with thickness of 1 mm and a length of 3x3 mm. The pores of matrices function receptacles, in which various chemical reactions can undergo. If a matrix is handled with a unique reagent it turns into an optode touchy to a selected substance. We plunge this optode into the water to test it or genuinely drip a few drops on it, and it changes its color. subsequently, there's a required element.

Sergey Muravyov, the scientific manager of the project, head of the TPU worldwide Laboratory superior Measurements, says: "The greater excessive the color is, the higher is the awareness of the substance,"

for instance, if water includes silver optode turns purple-crimson. in line with the scientist, such a method can come across substances even at very low concentrations in water.

"You dip optode into the water after which load it into the device analyzer. There a special digital tool gets optical signal and converts it into an electric 3-channel RGB-sign.

After this sign processing the device outputs the facts in digital form on the concentration of the searched substance. The evaluation takes location right away," the challenge manager says.

This method lets in the detection of virtually all metals, natural substances and various pharmacological retailers in water.

"Our method works with those materials with which interplay leads to shade exchange. certainly, this isn't the entire range of substances. but everyday techniques do now not exist. nowadays, the most extensively used method for chemical evaluation is spectrophotometry. A cutting-edge spectrophotometer charges about 500 thousand rubles, and it is a bulky stationary tool. Our device can obtain the equal excellent of measurements, but it's miles compact and may value about 30 thousand rubles on the marketplace placement," -- he says.

this type of device for rapid analysis is useful for environmental and associated offerings employees of business enterprises. for example, oil agencies can use the tool for the dedication of the tracers in the drilling fluid.
