摘要
研究了高锰酸钾KMnO4对池塘微囊藻毒素(MC-LR)的去除效果,探讨反应影响因素(高锰酸钾质量浓度、温度、pH值、反应时间)对去除率的影响。结果表明,高锰酸钾能有效地去除水中的微囊藻毒素。高锰酸钾对MC-LR的去除率与高锰酸钾投加的质量浓度、温度、反应时间成正相关,其中高锰酸钾质量浓度对去除率的影响最大;其次为温度和pH,当温度为35℃时,去除率可达96.65%,当pH为3时,去除率也达到了95.1%;反应时间对去除率的影响不太显著。正交试验的结果也进一步证明了这一点。
It attained the removal result of MC - LR oxidated by potassium permanganate, discussed the removal effection by affecting factors （the concentration of potassium permanganate, temperature, pH, reaction time）. The result is that the potassium permanganate ean remove the MC - LR in water effectively. The removal result of MC - LR oxidated by potassium permanganate is positive correlation with affecting factors（ the concentration of potassium permanganate, temperature, pH）. The greatest impact factor to removal is the concentration of potassium permanganate, then is tempeature and pH. When the tempeature is 35 degree,the removal is 96.65% ;when the pH is 3, the removal is 95.1%. The reaction time is not significant. The results of Orthogonal trial can prove these results.
