Dissolution of platinum which is incorporated in automotive catalytic converters is performed through chemical methods. There is a need to develop a cost-effective and environmentally friendly process for platinum dissolution. This poster summarizes research on the possibility of 10 HCl: 1 H2O2 solution to replace aqua regia for the mentioned task. Dissolution of platinum in this solvent was studied as functions of agitation rate, time, liquid/solid mass ratio and the reaction temperature. A comparison of the solvent's efficiency with that of aqua regia was provided at each step. It was demonstrated that 95% dissolution of platinum in catalytic converters could be achieved with 10 HCl: 1 H2O2 solution under moderate experimental conditions, which are easy-to-adopt to the industrial plants.
