【摘要】研究由浸渍法制备负载型Fe2O3/凹凸棒土催化剂,并利用该催化剂对印染废水进行处理,探讨废水pH值、催化剂用量、反应时间等对色度去除率的影响。研究结果表明,Fe2O3/凹凸棒土催化剂对印染废水有良好的处理效果,对废水的脱色率高达96.7%。更多还原

【Abstract】 In this paper,Fe2O3 / attapulgite catalysts were prepared by impregnation. Experimental results show that the pH value ,catalyst concentration and the time of reaction influence the treatment of dyeing wastewater, and that Fe2O3 / attapulgite catalysts could be used for the treatment of dyeing wastewater and decolorization rate is 96. 7%.更多还原
