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因素。实验结果表明 :当催化剂用量为 0 .0 0 1 g/ m L ,p H=3.7,NO2 - — N起始浓度为 40 0 .0 mg/ L时 ,光照 1 h,其氧化率可达 97.0 %。
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%.
