【摘要】 以自制纳米α-Fe2O3粉体为光催化剂,对苯胺的光催化降解进行了实验研究。讨论了光催化氧化法的反应机理及光催化剂的投入量、废水pH值、苯胺初始浓度、反应时间等因素对苯胺去除率的影响。研究表明:α-Fe2O3投加量为0.05gL/,溶液的pH值为8,苯胺的初始浓度为35mgL/时,光照4h后苯胺去除率可达92%左右。更多还原

【Abstract】 The photocatalytic degradation of aniline using α-Fe2O3 as photocatalyst has been studied in this paper.The main factors,such as adding quantity of α-Fe2O3,pH value,initial density of the aniline and time of degradation,were discussed for the removal efficiency of aniline.Furthermore,the optimal experiment condition has been defined.The results of the test show that when the adding quantity of α-Fe2O3 is 0.05 g/L,the pH value is 8,the initial density of the aniline is 35 mg/L,the time of degradation is 4 hours,the removal efficiency can reach 92%.更多还原
