涡流空化/Fenton协同降解溶液中活性艳红K-2BP
Degradation of brilliant red K-2BP in water by swirling cavitation combined with Fenton reagent
【摘要】 采用涡流空化(SC)/Fenton协同降解溶液中活性艳红K-2BP,探讨了H2O2、Fe2+、pH、涡流压力以及活性艳红K-2BP初始浓度对SC/Fenton降解效果的影响。结果表明,H2O2和Fe2+的浓度过高或过低都会降低活性艳红K-2BP的降解率,低pH环境有助于活性艳红K-2BP的降解,活性艳红K-2BP的降解率随涡流压力的增大而升高,随其初始浓度的增加而降低。当活性艳红K-2BP初始质量浓度为10mg/L,H2O2质量浓度为165mg/L,Fe2+摩尔浓度为1.5×10-4mol/L,pH为4.0,涡流压力为0.8MPa时,活性艳红K-2BP降解率可达91.81%。
【Abstract】 The degradation of brilliant red K-2BP in water by swirling cavitation (SC) combined with Fenton reagent was studied,and the effect of influence factors such as the concentration of H2O2 and Fe2+,pH value of solution,dye initial concentrations and swirling pressure on treatment efficiency were investigated.The results showed an obvious synergistic effect of SC/Fenton reagent for the dye degradation.It was found that the degradation of brilliant red K-2BP was strongly dependent on the concentration of H2O2 and Fe2+ and pH of the solution.It was also found that the degradation rate of brilliant red K-2BP increased with increasing pressure and decreasing the dye initial concentration.When the dye initial concentrations was 10 mg/L,H2O2 was 165 mg/L,Fe2+ was 1.5×10-4 mol/L,pH value of solution was 4.0 and under the swirling pressure of 0.8 MPa,the degradation rate of brilliant red K-2BP could reach to 91.81%.
