Latest Patents

Wenjihao Hu holds a patent for a method aimed at recycling copper-containing wastewater from micro-etching. This method involves modifying a FeS material with a monomer that includes both carboxyl and sulfhydryl groups, along with a crosslinking agent and a stabilizing and dispersing agent. The resulting FeS-based pH-responsive material, CMC-FeS@HS #SiO#COOH, is then added to weakly-acidic copper-containing wastewater. The process allows for a series of reactions, including sulfide precipitation, exchange, adsorption complexation, and flocculation precipitation, ultimately yielding a precipitate with CuS as the main component. This innovative method achieves a remarkable recovery rate of copper ions at 99.8% or more by simply adjusting the pH of the wastewater.
