摘要
采用超声波/H2O2降解水中酸性紫红染料,考察了超声波/H2O2的协同效应及超声功率、声密度、超声时间、染料初始浓度等因素对酸性紫红染料去除率的影响。结果表明,超声波/H2O2对酸性紫红染料的降解具有明显的协同作用,其去除率比超声波单独作用提高了40%。在一定的条件下,去除率随超声功率的增大而增加,随溶液体积的增加而减少,随超声时间的延长而增大,随染料初始浓度的增加而减少。
Ultrasonic/H2O2 has been used for degrading acidic violet. The synergistic effects of ultrasonic/H2O2, ultrasonic power, sound density, ultrasonic time, and initial concentration of the dyestuff on the removing rate are investigated. The results show that the synergistic effect of uhrasonic/H2O2 on the degradation of acidic violet is remarkable. Its removing rate is 40% higher than that of the effect by using ultrasonic alone. Under certain conditions, the removal rate increases with the increase of ultrasonic power, decreases with the increase of solution volume, increases with the extension of ultrasonic time, or decreases with the initial concentration of dyestuff.
