The aim of this work is to develop techniques of determining the optimal conditions of the synthesis of ionic associates of organic cations with heteropolyanions structure of Keggin. Research methods – spectrophotometry, amperometric titration and direct potentiometry. The investigated reaction ntloginmodule organic cation of thiabendazole with heteropolyanions structure Cena, indicating the formation of ion associates. The technique of definition of optimum conditions of synthesis of ionic associates of organic cations of thiabendazole with heteropolyanions structure of Keggin. By spectrophotometric and amperometric method thiruvanan the composition of the ion associate thiabendazole with heteropolyanions structure of Keggin depending on the conditions of synthesis determined by the product of solubility of the obtained low-soluble ion associates. It is established that the value of the works of solubility is quite low, so they meet one of the main requirements for electroactive substances in potenziometro sensor - low solubility in water. It is shown that the low solubility of these compounds determines their high sensitivity and selectivity, and also affects to increase the time life of the membrane sensor. Branch of use: C 20.59 - manufacture of other chemical products, n. in. and. in. ; M 72.19 - research and experimental development in the field of other natural and technical sciences.
