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. 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.
