The catalytic efficiency of transition metal oxides deposited on the polymer matrix has been investigated in sodium sulfide oxidation. Using known patents methods:heterogeneous catalysts were synthesized by introducing transition metal oxides into the polymer matrix, the concentration of Na2S was measured by the potentiometric titration method . It is shown that the polymeric catalyst based on copper and manganese oxides has highest activity in sodium sulfide oxidation. Complex optimal conditions, kinetic parameters of sodium sulfide oxidation in the presence of the mixture of copper and manganese oxides deposited on the polymer matrix have been determined. The mechanism of electron transfer between copper and manganese cations has been considered.
