    摘要:

    有机磷酸酯（OPEs）阻燃剂与重金属铬是电子垃圾拆解区环境中常见的复合污染物。研究300 W汞灯（λ=365 nm）照射下Fe （Ⅲ）在水溶液中同时光催化氧化磷酸三（2-氯乙基）酯（TCEP）和还原Cr （Ⅵ）的性能，考察Fe （Ⅲ）、Cr （Ⅵ）和TCEP初始浓度的影响，探讨UV/Fe （Ⅲ）体系中Fe （Ⅲ）/Fe （Ⅱ）氧化还原循环再生性，并验证UV/Fe （Ⅲ）对其他OPEs降解的适用性。结果表明：在UV/Fe （Ⅲ）体系中，光催化降解TCEP和还原Cr （Ⅵ）同时发生。Fe （Ⅲ）初始浓度的增加有利于Cr （Ⅵ）的光催化还原和TCEP的氧化降解。Cr （Ⅵ）的还原随着TCEP初始浓度的增加而增加，但不同Cr （Ⅵ）浓度对TCEP的降解效率影响并不明显。在UV/Fe （Ⅲ）体系中，5次循环实验都能实现TCEP的完全降解和Cr （Ⅵ）的还原。此外，该体系对其他OPEs与Cr （Ⅵ）的复合污染也有类似的光催化效果。Fe （Ⅲ）作为均相光催化剂可以处理含OPEs和Cr （Ⅵ）的复合污染。

    Abstract:

    Organophosphorus phosphate(OPEs)and hexavalent chromium (Cr(Ⅵ)) are common combined pollutants in electronic waste dismantling area.Simultaneous photooxidation of tris (2-chloroethyl) phosphate (TCEP) and photoreduction of Cr(Ⅵ) by ferric iron (Fe(Ⅲ)) in aqueous solution were studied under 300 W mercury lamp (λ=365 nm). The effects of the initial concentrations of Fe(Ⅲ), Cr(Ⅵ), and TCEP were investigated.The regeneration of Fe(Ⅲ)/Fe(Ⅱ) redox cycle in UV/Fe (Ⅲ) was studied. The applicability of UV/Fe(Ⅲ) to degradation of other OPEs was proved. The results showed that photocatalytic degradation of TCEP and reduction of Cr(Ⅵ) occurred simultaneously in UV/Fe(Ⅲ) system. The increased Fe(Ⅲ) initial concentration was beneficial to the photocatalytic reduction of Cr(Ⅵ) and the oxidation of TCEP.The reduction of Cr(Ⅵ) increased with the increasing TCEP initial concentration.However, the Cr(Ⅵ) concentrations had no significant effect on TCEP degradation.In UV/Fe(Ⅲ) system, TCEP can be degraded completely and Cr(Ⅵ) can be reduced in five cycles. Similar photocatalysis effects were observed for other OPEs. As a homogeneous photocatalytic method, UV/Fe(Ⅲ) can solve the combined pollution containing OPEs and Cr(Ⅵ) at the same time.
