APPLICATION OF THE CHOLINESTERASE BIOSENSORS IN THE ANALYSIS OF THE OBJECTS OF THE ENVIRONMENT AND CONTROL OF THE WATER QUALITY

The object of investigation: the potentiometric cholinesterase biosensors, phosphor-organic pesticides, natural and sewage waters of the number of chemical productions. The purpose of the work: the development of the constructions and optimization of functioning of the potentiometric biosensors for the determination of the water and plant materials contamination by pesticides, and evaluation of the common contamination (toxicity) of waters. Determined have been the laws of the biosensors functioning under the different experiment al conditions and depending on the composition of the ferments-containing membranes. Studied has been the effect of the mass-transfer conditions on the characteristics of the biosensors response. Developed have been the new electrochemical method of the samples preparation, containing the thion pesticides, the new methods of express-diagnostics of presence of the remaining quantities of the phosphororganic pesticides in the vegetation material. For the first time, the comparative tests of the cholinesterase biosensors and methods of biotesting and the field tests of biosensors intended for the water quality controlAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
