Application of HPLC and CZE to the analysis of polyoxometalates.
Polyoxometalates (POM) are polymers of transition metal oxides. They are widely used as analytical reagents and reaction catalysts. Some have anti-viral properties and are being investigated as anti-HIV agents. Due to solubility and stability limitations, separation methods for POM are rare in the literatures. This paper presents a HPLC and a CZE method for the analysis of sodium tungstate, its equilibrium products and isopolyanions. The methods are simple and sensitive, and can be used to monitor the purity, stability and solution equilibria of POM.
