摘要
以铁粉作催化剂、H2O2作氧化剂去除废水中的对氨基苯酚(PAP),研究了初始pH值、H2O2加入量、铁粉加入量及反应时间对PAP去除率的影响。确定最佳去除条件如下:初始pH值7.0、H2O2加入量2.0 mL、铁粉加入量1.7 g、反应时间80 min,在此条件下,PAP去除率可达93.6%。该法去除率高,不会带来二次污染,可用于较高浓度PAP废水的预处理。
The process of removal of p-aminophenol（PAP） in wastewater with iron chips as catalyst,H2O2 as oxidant was studied in this paper.The effects of initial pH value,H2O2 dosage,iron chips dosage,reaction time on PAP removal rate were investigated.The optimum conditions were obtained as follows： initial pH value 7.0,H2O2 dosage 2.0 mL,iron chips dosage 1.7 g,reaction time 80 min.Under above conditions,the PAP removal rate reached 93.6% with high removal efficiency,non-pollution.The method was especially appropriate to pretreatment of wastewater containing high concentration of PAP.
