摘　　要：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94.5×100μW/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。Degradation of Tris（1,3-dichloro-2-propyl） phosphate（TDCP） by UV / H2O2was 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 PO4 3-under the optimized conditions including 10 mg/kg of the initial concentration of TDCP, 94.5×100 μW / cm2of UV light intensity, pH of 7 and 5 mmol / L of H2O2with 60 min irradiation. The UV / H2O2system had high ability for oxidative degradation of TDCP.
