Description

Electromembrane preparation of H3PW12O40 was investigated. Using NMR 31P, 183W, and 17O data, transformations of isopoly- and heteropolytungstates were studied over the wide pH range. Depending the medium acidity and the kind of isopolytungstate, 2 pathways of interaction of isopolytungstates with phosphate ions during formation of H3PW12O40 are suggested
