Mironyak M. Electrochemical analysis of salts of polyhexamethyleneguanidine in industrial products

Work is describes application of electrochemical methods of analysis (amperometric titration and absolute potentiometry) at determination of salts of polyhgexamethylenguanidine (PGMG). On the basis of got results the amperometric method of determination of equivalent molecular mass of salts of PGMG and method of determination of quantitative content of salts of PGMG is developed in a substance and industrial products. Littlesoluble compounds of permanent composition are got with associative character of compounds of organic cations polyhgexamethylenguanidine and hexamethylenediamine from GPA used a in quality EAS for improved diaphragm ISE, circulating to organic cations of polyhgexamethylenguanidine and hexamethylenediamine. On the basis of findings the developed method of determination of quantitative content of salts of polyhgexamethylenguanidine (to the phosphate, to the chloride and glukonate) is in a substance and industrial objects by the method of absolute potentiometry with the use of developed ISE. Keywords: polyhexamethyleneguanidine, elektrod-active substance, ion-selective electrod, amperomethric titration, 12-molybdophosphoric heteropolyacid, hexamethylenediamine.
