The purpose of the work is the development of potentiometric sensors sensitive to cationic nitrogen-containing surfactants and preservatives, and methods for potentiometric determination of cationic nitrogen-containing surfactants and food and cosmetic preservatives using membrane sensors. Methods of study - potentiometry and spectrophotometry. The reactions of the interaction of 12-molybdophosphate heteropolyacid with the cations of nitrogen-containing surfactants and preservatives have been investigated and the ratio of the reacting components was established. Intermediate ionic associates were got. These ionic associates were used to develope of the potentiometric sensors reversible to cationic nitrogen-containing surfactants and preservatives. The influence of various factors on basic electrode properties was investigated. A new technical solution was proposed which allow us to submite 1 application for the issuance of a security document of Ukraine for the object of intellectual property (for utility model). The new, easy-to-perform, sensitive and express potentiometric method for the determination of cationic nitrogen-containing surfactants and preservatives in industrial products was proposed. 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.
