The purpose of the work is to develop a potentiometric sensor of reversible to nonionic and ampholytic surfactants and a method for potentiometric determination of nonionic and ampholytic surfactants using membrane sensors. Methods of research - direct potentiometry and spectrophotometry. The mechanism of the emergence of a selective response of potentiometric sensors with plasticized membranes containing as an electrodeactive substance is a soluble ion associates of nonionic and ampholytic surfactants with heterogeneous Keggin structures (12-molybdophosphate and 12-tungsten-phosphate heteropolyacids) and potentiometric sensors, reversible to nonionic and ampholytic surfactants. New technical solutions are proposed, for which 2 applications for the issuance of security documents of Ukraine to intellectual property objects are filed. A new sensitive, selective and express potentiometric method for the determination of nonionic and ampholytic surfactants in the composition of cosmetic products is proposed.
