摘要
研究了FeCl3的水解产物对亚甲基蓝溶液的紫外光催化降解性能,确定了反应溶液FeCl3的最佳浓度和pH值。发现FeCl3的水解产物随着溶液中FeCl3的浓度和溶液pH值的变化而不同,光催化率也随着水解产物的不同而改变。当溶液pH值=3.02,FeCl3的浓度为200mg/L时,光催化降解率达到最大值93.2%。
This paper mainly studied the effect of hydrolysis product of ferric chloride on photocatalytie degradation of methylene blue in acidic medium. Optimum concentration of FeCl3 and the suitable pH value of the sample solution were determined. It is found that once the concentration of ferric chloride and the pH value of the solution were changed the hydrolyzed products of ferric chloride should be different, caused the change of photo-degradation rate, Controlling the pH value of solution to 3.02 and the concentration of ferric chloride to 200mg/L, the photo-degradation rate reached a maximum value of 93.2%.
