Abstract

The invention provides a microelectrode integrated sensing chip and application in rapid detection of organic pollutants in water. According to the invention, a plurality of microelectrodes are integrated in the same detection area of an electrode substrate of a sensing chip and are conducted and connected with electrode contacts on the back surface of the electrode substrate, the surface of the microelectrode is modified with a nano-porous metal modification layer to realize electrochemical enzyme-free detection and electrode contact conduction of a three-electrode system to realize the purpose of simultaneously detecting a plurality of indexes at one time, and a micro box dam is arranged around the microelectrode to prevent a detection solution from overflowing out of a detection range to cause interference. The sensing chip can be used for rapid detection of organic pollutants in water.

Description

technical field

[0001] The invention belongs to the field of electrochemical detection, in particular to a micro-electrode integrated sensor chip and its application in rapid detection of water quality organic pollutants. Background technique

[0002] Water quality safety is the top priority of the country, and water environment safety is the foundation to ensure the safety of drinking water, among which organic pollution is an unavoidable problem in water quality analysis. The concentration of organic pollutants in water is very low, and routine water quality analysis is not easy to detect. The methods currently used for the detection of organic pollutants in water include: gas chromatography, gas chromatography-mass spectrometry, gas chromatography and Fourier transform infrared spectroscopy, high performance liquid chromatography, liquid chromatography-gas chromatography, etc. . However, the above analysis methods have problems such as long test time, untimely response,...
