Study On The Characeter Of Interactions Between Metal-Pyridylazo Resorcinol Complexes And Cationic Surfactants By Spectrophotometry And Liquid Chromatography

Abstract

Metal-pyridylazoresorcinol complexes are studied in micellar medium by using spectrophpotometric and chromatographic techniques. Study shows that divalent cations form uncharged complexes and are little affected by presence of charged surfactants. Metals with higher valence number like vanadium forms negatively charged complexes and due to the formation of ternary complexes with surfactant cause shift in peak position and peak intensity. Addition of surfactant enhances the selectivity of analysis.
