Description

technical field

[0001] The invention belongs to the technical field of environmental monitoring, and in particular relates to an electrochemical sensor and a device thereof which can be used for real-time monitoring and detection of water biological toxicity. Background technique

[0002] With the development of modern industry, the increasing environmental pollution has caused a great impact on the water ecosystem, and its toxicity detection has become an important link in the evaluation of water environment quality. At present, the methods used to test the toxicity of pollutants mainly include physical and chemical methods and biological methods. Physical and chemical methods such as liquid chromatography and atomic absorption spectroscopy can accurately and quantitatively analyze the content of a certain pollutant or a certain type of pollutant; however, the comprehensive impact of pollutants on the ecosystem is often not a simple sum of the toxicity of each single substa...
