APPLICATION OF CHEMILUMINESCENCE FOR THE DETERMINATION OF COMPOSITION OF ION ASSOCIATES OF HETEROPOLY ACIDS WITH CATIONIC SURFACTANTS

 Composition of sparingly soluble ion associates of molybdosilicic, molybdovanadoarsenic, and molybdovanadophosphoric heteropoly acids with long,chain cationic surfactants has been examined by equilibrium shift method and molar ratio method after filtration through the cellulose filters, applying chemiluminescence reactions of ion associates with luminol. Integral light amount and maximum light intensity were used as characteristics of the system. Molar ratio of components in ion associate determined by equilibrium shift method coincides with ratio found by molar ratio method.

Keywords: chemiluminescence, ion associates of heteropoly acids, compounds composition, equilibrium shift method, molar ratio method
