Cobalt/graphene carbon beads clear antibiotic pollutant from water without metal leaching
Researchers have developed a new cobalt-graphene carbon bead catalyst that effectively removes antibiotic pollutants from water without the metal leaching issues seen in previous methods. The honeycomb structure of the beads allows for a two-stage reaction that accelerates the breakdown of sulfamethoxazole.
Why it matters
This innovation provides a more sustainable and efficient solution for treating pharmaceutical contamination in water supplies.
Researchers at Hebei University of Technology, Nankai University, and the Oil & Gas Technology Research Institute of Huabei Oilfield Company have developed a millimeter-scale, magnetically recoverable carbon bead catalyst that achieves complete removal of the antibiotic sulfamethoxazole (SMX) from water within 20 minutes, while largely avoiding the metal leaching that has limited earlier cobalt-based catalysts for this kind of water treatment.
