Description

Formation of barely soluble compounds during interaction of ammonium and potassium tripolyphosphates with cadmium nitrate in aqueous solutions (0.1-2.0 mol% concentration, the temperature 20 deg C), is investigated. KCd2P3O10x7H2O, NH4Cd2P3O10x7H2O crystallohydrates and Cd5(P3O10)2xhH2O (x=10-13) X-ray amorphous salt, that are dissolved in potassium and ammonium tripolyphosphate solution with formation of Cd2+:P3O105-=1:1 and 1:2 complexes, are separated. In K5P3O10-Cd(NO3)2-H2O system Cd2+:P3O105-=1:1 complex is crystallized in a mixture with varied composition amorphous phase
