【摘要】 研究了影响超声波降解酸性橙Ⅱ的温度、浓度、超声波输出功率、pH值和二氧化钛添加量等各种因素,结果发现,温度升高降解率提高,质量浓度增大降解率降低,输出功率增加降解率升高,pH值下降降解率升高,二氧化钛添加量增加降解率升高,在0.75 mg.L-1时,效果最好;并进一步研究了降解机理,发现其降解符合一级动力学规律。更多还原

【Abstract】 Factors influencing degradation of acid orange Ⅱsuch as temperature,concentration,ultrasonic output,pH,quantity of TiO₂ were studied.The experimental results showed that the rate of degradation was improved when the temperature raised;the rate of degradation was declined when the concentration was increased;the rate of degradation was increased when the output power was enlarged;the degrading rate went up when the pH descended;the rate was raised when the amount of TiO₂ increased,and the rate reached the highest value at 0.75?mg/L.After further investigation,it is found that the degradation of acid orangeⅡ obeys the one-class dynamics更多还原
