中文摘要 | 以有机磷农药-草甘膦为目标污染物,利用光电芬顿方法对其进行降解研究。研究汇总考察了电流强度、初始pH、Fe~(2 +)浓度、草甘膦初始浓度、光种类及通入背景气体种类对草甘膦降解效果的影响。实验结果表明:电流强度越大,草甘膦初始浓度越低,草甘膦降解效果越好;草甘膦在pH = 2.0 ~ 3.0的酸性体系中降解效果最好; Fe~(2 +)浓度升高,草甘膦降解效果增强。在电流为0.36 A、初始pH = 3.0、Fe~(2 +)浓度为1.0 mmol·L~(- 1)、通入100 mL·min~(- 1) O_2条件下,以365 nm紫外光照射的光电芬顿反应降解初始浓度为84.5 mg·L~(- 1)的草甘膦溶液,处理360 min后溶液矿化率可达64.5%。 |
英文摘要 | Effects of current density,initial pH,Fe~(2 +) concentration,initial glyphosate concentration,irradiation source,and input gas on GS degradation by the photoelectro-Fenton (PEF) process were discussed. The results showed that better GS degradation was achieved with a higher current density and a lower initial concentration of GS; higher degradation in the PEF system was achieved when the initial pH was 2.0 to 3h. 0; degradation of GS was enhanced when the Fe~(2 +) concentration increased. Under the optimum conditions of 0.36 A,pH = 3.0,1.0 mmol·L~(- 1) Fe~(2 +), 100 mL·min~(- 1) O_2,when the initial GS concentration was 84.5 mg·L~(- 1),the electro- Fenton along with UVA irradiation process can mineralize GS efficiently,and the TOC removal is up to 64.5% after 360 min of treatment. |
