METHOD OF DETERMINATION OF ANIONIC SURFACE-ACTIVE SUBSTANCES Russian patent published in 1995 - IPC

Abstract RU 2041460 C1

FIELD: analytical chemistry. SUBSTANCE: method involves processing of analyzed solution with pH 4-10 and equal-weight concentration of tris-(1,10-phenantrolin) iron of (2+)chloride 5·10^-5-5·10^-4 m, precipitation of stained ion associate on to foam polyurethane and subsequent measurement of its diffusion reflection. EFFECT: improved accuracy of analysis.
