摘要
利用半导体光催化剂Bi2 O3对含亚硝酸盐废水的处理进行了研究 ,并讨论了影响亚硝酸盐氧化率的主要因素 .实验结果表明 :选择活性较高的Bi2 O3作为光催化剂 ,当其用量为 0 .0 50 g ,试液 pH =3 .70 ,NO2 - —N起始浓度为4 0 0 .0mg/L ,光照 1h时 ,亚硝酸盐的氧化率达到 97.0 % .
The treatment of waste water containing nitrite over Bi 2O 3 is studied.The primary factors which influence the oxidation efficiency of nitrite are discussed.The results show that the oxidation efficiency of nitrite can reach 97.0% by using Bi 2O 3 as photocatalyst,with its quantity of 0.050 g,pH of 3.70,the nitrite's initial concentration of 400.0 mg/L,illumination time of 1 h.
