  • 摘要: 研究了低分子有机羧酸草酸、柠檬酸对内分泌干扰物双酚A(BPA)在累托石悬浮液中光降解的影响.结果表明,在250W金属卤化物灯(λ≥360nm)照射下,草酸、柠檬酸可以显著提高BPA在累托石悬浮液中的光降解率,反应符合Langmuir-Hinshelwood动力学方程,降解率同时受pH值、累托石用量的影响,矿化实验表明BPA在累托石/低分子羧酸体系中能够深度氧化.
    Abstract: Effects of low molecular organic carboxylic acids on the photoegradation of bisphenol A(BPA)in rectorite suspensions under UV-vis irradiation were carried. It was found that the BPA photodegradation could be greatly enhanced in the presence of oxalate or citrate in rectorite suspensions. The photodegradation rate of BPA was fitted well into the Langmuir-Hinshelwood equation,and the ratio of photodegradation was dependent on the pH of the solution and the rectorite dosages. Results of mineralization also indicated that the mineralization efficiency was efficiently affected by the oxalate.
