Platinum group metals (PGMs) are increasingly recycled from spent automotive catalysts due to their scarcity in nature. Many studies were developed using different leaching reagents to achieve greener benefits and reduce environmental pollution. This article reports for the first time a direct comparison of leaching reagents on the efficiency of PGMs using microwave (MW) assisted heating. The leaching system employed HCl with/without the addition of complexing (citric acid) or oxidizing agents (HNO
