Abstract

Abstract An antibiotic zeolite and an antibiotic resin composition containing thereof are provided. The antibiotic zeolite is prepared by replacing all or a part of ion-exchangeable ions in zeolite with ammonium ions and antibiotic metal ions such as silver, copper, zinc, mercury, tin, lead, bismuth, cadmium, chromium and thallium. The antibiotic resin composition comprises the antibiotic zeolite and a resin such as polyethylene, polypropylene, polyvinyl chloride and polystyrene.
