摘 要: 研究H2O2投加量、卡马西平初始浓度、UV辐照强度、初始pH和共存阴阳离子对卡马西平降解速率的影响。实验结果表明:单独UV辐照对卡马西平基本没有去除效果,而UV/H2O2联合工艺能够有效地去除卡马西平;卡马西平的降解速率随着H2O2投加量的增大而增大,随着卡马西平初始浓度的增大而降低;增强UV辐照强度能够显著提高卡马西平的降解速率;酸性和中性条件有利于UV/H2O2工艺对卡马西平的降解;水中阴离子对卡马西平的降解存在不同程度的抑制作用,抑制程度遵循如下顺序(由大至小): , , ,Cl-, ;Fe3+能够显著地促进卡马西平的降解。

Abstract:The effects of H2O2 dosage, initial carbamazepine concentrations, UV irradiation intensity, initial pH of solution, coexisting anions and cations on photochemical degradation of carbamazepine in water were studied. The results show that UV alone can not degrade carbamazepine. However, UV/H2O2 combined process can degrade carbamazepine effectively. The degradation rate of carbamazepine increases with the increase of the H2O2 dosage; the degradation rate of carbamazepine decreases with the increase of the initial carbamazepine concentrations. Enhancing UV radiation intensity can greatly improve carbamazepine degradation rate. The degradation of carbamazepine performs well in acidic and neutral conditions. Coexisting anions exhibit different degrees of inhibition effects, the degree of inhibition abiding from strong to weak by the following order: , , , Cl- and , and Fe3+ can significantly improve the degradation rate of carbamazepine.
