| dc.description.abstract | Based on their economic importance and supply risk, platinum group metals (PGMs) are classified as critical elements by the European Commission. Meeting the increasing demand for PGMs is becoming more and more difficult due to the limited natural resources and depletion of high-grade ores [1,2]. A catalytic converter contains 0.1-0.5% PGMs such as Pt, Pd, and Rh, and the PGM content in catalytic converters is approximately a thousand times higher than the amount found in the ore [2]. For this reason, it is of great importance to obtain PGMs from non-traditional materials, such as scrap autocatalytic converters. This work aims to obtain high-efficiency, environmentally friendly, and economical PGM from the scrap catalytic converters with hydrometallurgical method. The scrap catalytic converter sample purchased from a Turkish supplier company in ground form was analysed to determine its PGM content. In order to investigate the roles of leaching temperature, T, solid to liquid ratio, S/L, and leaching time, t, the samples were treated with HCl and H2O2 solution under different leaching conditions. During leaching step, more than 98% Pt and Pd were taken into solution while Rh was leached more than 60% efficiency. Following the leaching step, the elements were separated from the leach solution by precipitation. | |
