Medvetskii, T. Tikhomirova, A. Smolenkov, E. Shapovalova, O. Shpigun] Conditions were found for the group adsorption preconcentration of phosphomolybdic and silicomolybdic heteropoly acids (HPAs) in the dynamic mode on a microcolumn packed with an Amberlite XAD-8 polyacrylate adsorbent. A sorption-chromatographic method for determining phosphate and silicate ions in waters as molybdic HPAs is developed. It is based on the adsorption of HPAs followed by desorption with acetonitrile and determination by reversed-phase HPLC. The detection limits for phosphorus and silicon calculated by the 3s test were 0.5 and 0.1 μg/L, respectively. Pleiades Publishing, Ltd., 2007 Medvetskii A.
