摘要
研究了pH值,Fe2+浓度,H2O2浓度以及有无超声波条件的对胭脂红催化降解速率的影响。结果表明:随着模拟废液的pH值的增大,胭脂红的降解速率呈下降趋势。Fe2+的最佳浓度为5×10-3mmol/L,而H2O2的最佳浓度为5×10-2mmol/L;无论是大于或是小于最佳值浓度均会导致胭脂红降解速率的下降。在超声波存在的条件下可以明显的加快降解速率。
The effect of pH, Fe^2+, H2O2 concentrations and ultrasound on the ratio of degrading carmine were studied. The experimental results shown that the degradation rate of carmine is slow when pH value is decreasing. The optimum concentrations of Fe^2+ and H2O2 are 5 × 10^-3 and 5×10^-2 mol/L respectively,and ultrasound was used to increase obviously the ratio of degrading carmine.
