Researchers develop new method to easily recover palladium, silver from industrial waste

Researchers develop method to recover palladium, silver from industrial waste Industrial waste. (Reference image by terimakasih0, Pixabay). Researchers from Kanazawa University in Japan have developed a mechanism to improve the recovery of silver and palladium ions from aqueous acidic waste. Chemical Engineering Journal, the scientists said that the process they developed involves chemically modifying ultrasmall particles of cellulose – an abundant and nontoxic biopolymer – to selectively adsorb silver and palladium ions at room temperature. Adsorption was nearly complete at acidic pH with acid concentrations of around 1 to 13% by volume.

Simple and Cost-effective Extraction of Rare Metals from Industrial Waste

Date Time Simple and Cost-effective Extraction of Rare Metals from Industrial Waste Researchers from Kanazawa University developed a protocol to efficiently purify palladium and silver ions from industrial waste, and convert the ions into pure metallic elements. This will help increase global stock of valuable elements that are widely needed yet in scarce supply. Kanazawa, Japan – Many rare metals are in scarce supply, yet demand for use in electronics, medical instrumentation, and other purposes continues to increase. As waste, these metals pollute the environment and harm human health. Ideally, we would recycle the metals from waste for reuse. Unfortunately, current recycling methods are some combination of complex, expensive, toxic, wasteful, and ultimately inefficient.
