| 摘 要： | 利用半导体光催化剂Ｂｉ２Ｏ３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因素。实验结果表明，当催化剂用量为０．００１ｇ／ｍＬ，ｐＨ＝３．７，ＮＯ２－Ｎ起始浓度为４００．０ｍｇ／Ｌ时，光照１ｈ，其氧化率可达９７．０％。

| Abstract: | This paper reports the treatment of nitrite bearing wastewater by semiconductor photocatalyst Bi 2O 3. The factors which influence the oxidation efficiency of nitrite are discussed. The experiment result shows: when catalyst quantity= 0.001 g/mL, pH=3.7, the starting concentration of nitrite N=400.0 mg/L, illumination 1 h. the oxidation efficiency of sodium nitrite can reach 97.0%. |
