摘要
研究采用UV、H2O2、草酸高铁铵体系处理甲苯胺蓝(Toluidine blue,简称为TB)溶液的降解作用。考察了TB初始浓度、初始pH值、H2O2浓度、草酸高铁铵浓度对TB降解率的影响。试验结果表明,酸性条件有利于TB的降解,其最佳降解pH值为4.0。在UV/H2O2体系中,H2O2浓度在100 mmol/L时,TB降解率相对高;UV/草酸高铁铵体系中,草酸高铁铵浓度为10.0 mmol/L时TB降解率较高;相比于其它体系,UV/H2O2/草酸高铁铵体系的降解效果最好,降解率可达88.62%。
The influences of initial concentration of TB, initial pH value and dosages of H202 and ammonium ferric oxalate on degradation of TB are investigated. The results show that acidic condition tends to promote the degradation of TB, especially at pH value of 4.0. In UV/H2O2 system and UV/ammonium ferric oxalate system, the degradation of TB is relative higher with the concentration of H2O2 100 mmol/L and ammonium ferric oxalate 10.0 mmol/L respectively. Compared to other systems, UV/H2O2/ammonium ferric oxalate system show the highest degradation rate of TB with 88.62%.
