摘要: 研究了二硫代氨基甲酸改性玉米淀粉(DTCS)及其捕集重金属后产物在水体中的稳定性,考察了氧化剂、光催化氧化等不同方法下的降解效果.确定了降解的最佳反应条件.当氧化剂和紫外光共同作用时,降解效果更好.对降解产物的定性、定量分析结果表明,降解产物无毒,该水处理剂在水体中可安全降解.Abstract: The stability of DTCS and DTCS-Cu on the condition of oxidant and light photocatalysis oxidation are studied in this essay.The best degradation conditions are determined.Oxidant and UV together can make better effect.Qualitative and quantitative analysis prove that: the degradation products are nontoxic and can be safely degraded in the water.
