Selective Recovery of Platinum Group and Precious Metals from Waste Streams
This research community develops chemical methods to extract and separate platinum, palladium, gold, and rhenium from spent catalysts, electronic waste, and industrial liquid waste.
The work centers on designing selective adsorbents and extraction agents—specifically covalent organic frameworks, ionic liquids, and functionalized polymers—to isolate target metals from complex aqueous solutions. Recurring methods include solvent extraction, acid leaching, and adsorption using materials engineered for high selectivity. The primary feedstocks are spent automotive catalysts and end-of-life electronics. The goal is to recover high-value metals efficiently while minimizing the use of harsh reagents like hydrochloric and nitric acid.
The community represents the largest share of tracked research for Rhenium (7.4%), Technetium (6.3%), and Platinum (3.6%). Rhenium also contributes the highest number of papers to this group, with 1,041 entries.
The community comprises 6,030 papers, published most frequently in Separation and Purification Technology, Hydrometallurgy, and Analytica Chimica Acta.
Recent work focuses on covalent organic framework aerogels and porous organic networks for the selective capture of gold and palladium from e-waste leachates and wastewater.
