| Abstract: | The kinetic parameters of the heterophase processes were determined by the rotating disk equiaccessible surface method. The mechanism of the rate-determining step was shown to depend on the molar ratio between reagent concentrations. The ratios at which the highest reaction rates were observed can be used to prepare combined solvents for extracting silver and gold from natural and secondary raw materials. |
