| 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. |
