Description
Abdullah Al-Bogami and co-authors design a resin that pulls silver ions out of wastewater, in a 2025 study. Silver in factory effluent is both a pollutant and a lost resource. Their resin carries sulfur and nitrogen sites that grip silver tightly. Lab tests measured how much silver the resin can hold and how fast it takes it up. Computer models of the binding filled in the atomic picture.
The resin showed a very high uptake capacity and fast, chemistry-driven binding. Heat made the uptake stronger rather than weaker. Models showed silver prefers the sulfur sites, forming stable single-metal complexes. The resin kept about ninety-six percent of its power after five reuse cycles. It also favored silver over other ions in mixed water. The authors offer the design as a template for future cleanup materials.
