摘　　要：利用聚丙烯酸钠胶体溶液为模板,通过离子交换反应,形成尺寸约为70 nm的聚丙烯酸镉纳米球;然后与硫化钠反应,制备了表面为硫化镉量子点的纳米球,TEM对聚丙烯酸镉与硫化镉形貌进行了表征。在模拟可见光的条件下,聚丙烯酸-硫化镉纳米球可在5 min内将亚甲蓝降解85.7%。Using sodium polyacrylate colloidal solution as template, poly(acrylate acid cadmium salt) nanospheres with a size of about 70 nm were formed by ion exchange reaction. Then the nanospheres were dispersed in methanol soluting and reacted to prepare new nanospheres with sodium sulfide. The morphology of poly(acrylate acid cadmium salt) and cadmium sulfide/polyacrylic acid was characterized by TEM. Under the conditions of simulating visible light, polyacrylic acid-cadmium sulfide nanospheres can degrade methylene blue within 5 min by 85.7 %.
