Doctoral Research: Hydrometallurgical Recycling of Electronic WasteÂ
My doctoral research focused on the development of Polymer Inclusion Membrane (PIM)-based separation technology for the selective recovery of critical and precious metals from waste printed circuit boards (WPCBs). The research complemented conventional hydrometallurgical recycling processes by targeting trace metals such as nickel, zinc, lead, palladium, and platinum, which are often overlooked or remain as impurities during the recovery of high-value metals like gold and copper.
The developed PIMs provided an environmentally friendly and highly selective approach for simultaneous extraction and stripping of metal ions, offering advantages over conventional solvent extraction and ion-exchange processes. The work aimed to improve metal purity, enhance overall resource recovery, and reduce the environmental impact of electronic waste recycling.
