以磷酸三(1,3-二氯-2-丙基)酯(TDCP)作为研究对象,探索了TDCP的紫外光氧化高效降解方法。结果表明,紫外光光强对TDCP的降解有很大的影响。当TDCP初始浓度为10 mg/kg,紫外光光强为94.5伊100滋W/cm2,反应时间为60 min,加入H2O2浓度为5.00 mmol/L,溶液起始pH为7时,TDCP的TOC去除率为93.69%,有机氯、有机磷完全转化为Cl-和PO43-；UV/H2O2体系能有效的降解TDCP。
以燐痠三(1,3-二氯-2-丙基)酯(TDCP)作為研究對象,探索瞭TDCP的紫外光氧化高效降解方法。結果錶明,紫外光光彊對TDCP的降解有很大的影響。噹TDCP初始濃度為10 mg/kg,紫外光光彊為94.5伊100滋W/cm2,反應時間為60 min,加入H2O2濃度為5.00 mmol/L,溶液起始pH為7時,TDCP的TOC去除率為93.69%,有機氯、有機燐完全轉化為Cl-和PO43-；UV/H2O2體繫能有效的降解TDCP。

Degradation of Tris (1,3-dichloro-2-propyl) phosphate (TDCP) by UV/H2O2 was investigated and the influencing parameters were discussed. The results showed that intensity of UV light was the dominant parameter affecting the degradation of TCEP. 93.69% of total organic carbon (TOC) removed was achieved and organochlorine and organophosphorus were entirely transformed to Cl- and PO43- under the optimized conditions including 10 mg/kg of the initial concentration of TDCP, 94.5í100μW/cm2 of UV light intensity, pH of 7 and 5 mmol/L of H2O2 with 60 min irradiation. The UV/H2O2 system had high ability for oxidative degradation of TDCP.
