摘要
A spent Pt-NiO/Al2O3 industrial catalyst was examined with respect to Pt recovery. Aluminum chloride solutions, with low concentrations of nitric acid as an oxidant, were used instead of ''aqua regia''. The effect of aluminum chloride and nitric acid concentrations on the yield of platinum dissolution was studied. The substitution of hydrochloric acid by aluminum chloride, with low nitric acid concentration, does not affect the platinum dissolution yield, but minimizes excess reagents consumption.
