摘要：

A new principle of flow injection analysis using a precipitation reaction is suggested. It is based on a change of the equilibrium between solution and slightly soluble compound when passing the solution studied through a reaction column, containing a slightly soluble compound. H2PtCl6 is determined with a column containing Tl2PtCl6. The detection is performed by the current of thallium(I) oxidation to thallium(III) on a platinum electrode. Two different flow injection schemes are used. The determination of platinum(IV) is applied to platinum analysis in spent industrial alumoplatinum catalysts.
