| 摘 要： | 研究高铁酸钾对微囊藻毒素（MC—LR）的去除效果，探讨不同反应影响因素（反应时间、K2FeO4质量浓度、温度和pH）对去除率的影响。结果表明，K2FeO4能够有效地去除水中的MC—LR。K2FeO4对MC—LR的去除率与K2FeO4。投加质量浓度、反应时间成正相关，其中K2FeO4质量浓度对去除效果的影响较为明显；反应温度对去除率的影响不显著；pH对去除率也有重要影响，当pH分别为2和10时去除率分别为94．51％和87．96％。正交试验的结果也进一步证明了不同反应影响因素对去除效果的影响显著程度。

| Abstract: | Focus on efficiency of microcystin-LR removed by K2FeO4 and discuss effect of affecting factors of reaction such as reaction time, concentration of K2FeO4 , temperature and pH value on removal efficiency. The result showed that K2FeO4 can effectively remove microcystin-LR. Efficiency of removal was direct proportion on concentrates of K2FeO4 and reaction time. And the concentration of K2FeO4 had an important effect on the efficiency of removal. Temperature could not affect efficiency of removal obviously. The pH value was one of the most important factors affecting the efficiency of removal. Efficiency of removal was 94.51% or 87.96% when pH value was 2 or 10. Perpendicular test results confirmed it. |
