摘要: In acidic solution only molybdenum(VI), tungsten(VI), vanadium(V), niobium(V) and tantalum(V) form stable, anionic complexes with dilute hydrogen peroxide. This fact has been used in developing an analytical method of separating tungsten(VI) vanadium(V) from other metal ions each other. Preliminary investigations using reversed-phase paper chromatography solvent extraction led to a column Chromatographic separation technique. These metal-peroxy anions are retained by containing liquid anion-exchanger (General Mills Aliquat 336) solid support. Then selectively eluted aqueous solutions peroxide varying concentrations sulphuric acid.
