摘要
研究了D201和ZGA451阴离子树脂对含铬(VI)废水中铬离子的去除能力。试验结果表明,最佳静态吸附铬的工艺条件是:温度为30℃,吸附时间为12 h,D201最佳吸附p H为6,而ZGA451最佳p H则在4左右,搅拌能加快离子交换反应的速率。
The removal ability of D201 and ZGA451 anion resin for chromium ion in wastewater was studied. Through experimental study, the optimum process conditions for the static adsorption of chromium were obtained： the temperature was 30℃, the adsorption time was 12 hours. For D201, the best adsorption of pH was 6, while the ZGA451 was around 4. The rate of ion exchange reaction for Cr（Ⅵ） can be accelerated by stirring.
