摘　　要：通过单因素实验法,研究了初始浓度、过硫酸盐浓度和溶液pH对电晕放电等离子体协同过硫酸盐对于水中烟嘧磺隆处理效果的影响,以期找到对处理效果影响最大的因素,并对电晕放电的降解机理进行了分析。实验结果表明,样品的初始浓度、过硫酸盐浓度对于等离子体处理烟嘧磺隆的影响较小,pH对于烟嘧磺隆处理效果影响较大,处理烟嘧磺隆的最佳条件为电源电压24 kV,初始浓度40 mg/L,过硫酸盐浓度3.5 g/L,pH5。In this paper, the effects of initial concentration, persulfate concentration and solution pH on the treatment of fumisulfuron in water by corona discharge plasma and persulfate were studied by single factor experiment, in order to find out the most influential factors, and the degradation mechanism of corona discharge is analyzed. The experimental results show that the initial con-centration and persulfate concentration of samples have little effect on the plasma treatment of fumisulfuron, while pH has a great effect on the treatment effect of fumisulfuron. The optimal con-ditions for the treatment of fumisulfuron are 24 kV power supply voltage, 40 mg/L initial concen-tration, 3.5 g/L persulfate concentration, pH5.
