Abstract


It has studied conplexation chloroxamineazo F with heavy nonferrous and the precious metals in sulfuric and chloride solutions. Photometric characteristics of reactions are determinated. It has found that when heated with Sn(II) chloride complex of palladium is not dissolve, in contrast to a reagent that dissolves with formation unpainted products. This effect is a promising for the development of sensitive photometric methods for determination of palladium.

Key words
