FIELD: analysis of various chemicals, detergents, process solutions, and waste water. SUBSTANCE: method involves potentiometric titration of sample being analyzed using ion-selective solid-contact indicting electrode incorporating ion associate (cetyl pyridine - tetraphenylborate) and comparison silver chloride electrode. Cetyl pyridine is used as titrant for anion surface-active materials and sodium tetraphenylborate, for cation and non-ionogen materials. Non- ionogen surface-active materials are titrated in the environment of barium. EFFECT: enlarged range of surface-active materials detected. 5 tbl, 6 ex
