Reactive dye BES golden yellow simulated wastewater was treated with H(2)O(2)-assisted photolysis method. Influences of factors such as reaction time, initial pH and H(2)O(2) dosage were investigated, and the reaction kinetics of the process were explored. Results showed that, the degradation of 200 mg/L BES golden yellow solution happened only in the presence of both conditions: UV irradiation and H(2)O(2) addition. Initial pH and H(2)O(2) dosage had remarkable influence on the removal efficiency of the dye. Through several groups of univariate experiments, the optimum pH and H(2)O(2) dosage of the photolysis process were found to be 6-7 and 0.0375 mL 30% H(2)O(2) per milligram of BES golden yellow, respectively. The photolysis process was approximately in accordance with the second-order kinetic equation.
采用 H(2)O(2)-辅助光解方法处理 BES 金黄碱性染料模拟废水。考察了反应时间、初始 pH 值和 H(2)O(2)用量等因素的影响，并探讨了该过程的反应动力学。结果表明，只有在 UV 照射和添加 H(2)O(2)这两种条件同时存在的情况下，200mg/L 的 BES 金黄碱性染料溶液才会发生降解。初始 pH 值和 H(2)O(2)用量对染料的去除效率有显著影响。通过几组单因素实验，发现光解过程的最佳 pH 值和 H(2)O(2)用量分别为 6-7 和 0.0375 毫升 30% H(2)O(2)每毫克 BES 金黄碱性染料。光解过程近似符合二级动力学方程。
