摘要: CuO/γ-Al2O3类Fenton试剂是降解丁基黄药的优良试剂。该试剂与传统的Fenton试剂相比，提高了反应的pH值，可在较高pH（4~5）条件下反应，而传统的Fenton试剂的适宜pH值一般在3以下。采用单因素实验和正交实验相结合的方法研究了pH、催化剂投加量、过氧化氢投加量以及反应时间对丁基黄药降解效果的影响，并对催化剂的使用寿命进行了探讨。研究结果表明，反应的最佳条件为：pH为4~5，催化剂投加量为6 g/L，过氧化氢用量为30 mg/L，反应30 min。在此反应条件下，丁基黄药的降解率达98%以上；影响丁基黄药降解效果的因素大小顺序为：pH>反应时间>H2O2用量>催化剂投加量，其中pH对CuO/γ-Al2O3类Fenton试剂降解丁基黄药的影响最为显著。

Abstract: Fenton-like reagent composed by H2O2 and CuO/γ-Al2O3 has very good oxidation and degradation effect on butyl xanthate.Compared with the traditional Fenton reagents,CuO/γ-Al2O3 can mediate Fenton-like reaction over high pH value (4~5),while the pH value of traditional Fenton reagent is less than 3.The effects of pH,catalyst dosage,hydrogen peroxide dosing quantity and reaction time were studied with single-factor experiment and orthogonal experiment.The service life of the catalyst was also primarily discussed.The results showed that the optimal reaction conditions are as follows:pH of 4~5,catalyst dosage of 6 g/L,hydrogen peroxide of 30 mg/L,and the reaction time of 30 minutes.Under the optimal reaction conditions,the degradation rate of butyl xanthate reached up to more than 98%.The effect importance of the factors on degradation rate of butyl xanthate is pH,reaction time,hydrogen peroxide and catalyst dosage in turn,and effect importance of the pH is greatest.
