分析了3种常见的无机阴离子(SO 2－4、Cl－、NO －3)对 UV-铁(Ⅲ)-丙二酸体系中铁价态转化和邻苯二甲酸二甲酯(DMP)降解率的影响以及两者之间的机理联系。在 pH＝3、高氯酸铁与丙二酸配比为1∶10的条件下进行光降解。结果表明，在 UV-铁(Ⅲ)-丙二酸体系中，无机阴离子不但对铁价态之间的转化有显著影响，而且对DMP 的降解也有一定影响。在探讨无机阴离子对铁价态之间的转化影响的研究中，分别以存在与不存在 DMP 两种条件下进行讨论。在探讨无机阴离子对 DMP 的影响研究中，结果表明，无机阴离子对 DMP 的降解作用表现为：SO 2－4和 NO －3对 DMP 的降解率有微弱的促进作用，而 Cl－对 DMP 的降解率无显著影响。

In this paper,the effects of three kinds of common inorganic anions (SO 2 -4 、Cl- 、NO -3 )on the conversion of iron,the degradation of DMP and the mutual mechanism were observed in the system of UV-iron (Ⅲ)-malonic acid.The condition of photodegradation was conducted when the pH=3,the ratio of Iron (Ⅲ)perchlorate hydrate and malonic acid is 1∶10.The results showed that in the system of UV-iron (Ⅲ)-malonic acid,inorganic anions not only have a significant impact on the conversion of iron but also have some impact on the degradation of DMP.When exploring the effects of inorganic anions on the conversion of iron,whether there were DMP or there no the two conditions between the discussions.Experimental re-sults showed that the degradation of inorganic anions on DMP:SO 2 -4 and NO -3 have a weak role in promo-ting the degradation rate of DMP,while Cl- has no significant impact on the degradation rate of DMP in studying the impact of inorganic anions on the DMP experiments.
