Latest Patents
Han’s notable patent is titled "Method for recycling copper-containing wastewater from micro-etching." This innovative approach involves modifying a FeS material with a unique monomer that consists of both carboxyl and sulfhydryl functional groups, together with a crosslinking agent and a stabilizing dispersant. The resulting FeS-based pH-responsive material, designated as CMC-FeS@HS #SiO#COOH, is added to weakly acidic copper-containing wastewater, facilitating a series of reactions. These reactions include sulfide precipitation, exchange, adsorption complexation, and flocculation precipitation, ultimately yielding precipitates with CuS as the primary component. Remarkably, this method allows for a copper ion recovery rate exceeding 99.8% by merely adjusting the pH of the wastewater.
