摘要
本文利用半导体光催化剂Bi_2O_3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0.050g/50ml,PH=3.7,NO_2^-—N起始浓度为400.0mg/l时,光照1小时,其氧化率可达97.0%。
This paper reports the treatment of wastewater of nitrite with semiconductor Bi_2O_3. The factors which influence the oxidation efficiency of nitrite are discussed. The experiment result shows: at catalyst quantity=0.050g/50ml, PH=3.7, the starting concentration of nitrite—N=400.0mg/l, illumination 1h, the oxidation effciency of sodium nitrite can reach 97.0%.
