超声条件下海绵铁降解活性蓝194的研究

Degradation of Reactive Blue 194 in Water by Sponge Iron under Ultrasound

研究了超声波条件下,海绵铁对活性蓝194的降解,发现此条件下降解速度显增,且活性蓝194的降解遵循一级动力学。降解影响因素有海绵铁的用量和颗粒大小、溶液的pH值、超声波功率以及染料活性蓝194的初始浓度。结果表明随着海绵铁用量增加、粒度的增大、溶液初始pH值及初始浓度的增加,其降解速率也有所增加。

Degradation of Reactive Blue 194 by sponge iron under ultrasound has been investigated,and found that the degradation rate was significantly increased under this condition. Degradation of Reactive Blue 194 followed pseudo-first-order kinetics.The degradation factors was the dosaget of sponge iron,particle size of sponge iron,pH of solution,and ultrasonic power and the initial concentration of dye reactive blue 194. Results show that with the increase of dosage of sponge iron,the increase of particle size,initial pH solution,and the increase of initial concentration,the degradation rate also increased.
