AbstractA spent catalytic converter was treated with concentrated HCl and hydrogen peroxide in very mild conditions to extract approximately half of its platinum group metals (PGMs) content, mainly as chlorides. The noble metals were subsequently charged into functionalized mesoporous silica by complexation with mercapto groups.

Resource Recovery of Cerium from Spent Catalytic Converter Using Aqueous Metallurgy
2021Cerium recovery from a secondary waste stream generated after the extraction of Pt-group metals from spent catalytic converter has been investigated. Different mineral acids alone used as lixiviant could leach only 33% cerium; however, HF added acid mixture showed an increased leaching up to 96%.

Purification
Platinum group metals (PGMs), platinum (Pt), palladium (Pd) and rhodium (Rh), are critical for automotive emission control, chemical manufacturing and emerging energy technologies, yet their supply is limited and geographically concentrated.

Recovery of platinum group metals from automobile catalytic converters
Platinum has played important roles in human life due to their specific physical and chemical properties. The demand of platinum was reported to be continuously increasing, especially the use in automobile catalytic converters, while natural resources of
