通过对比几种常用的离子交换树脂,筛选出处理高氯酸铵溶液的最佳树脂;考察不同试验条件对树脂吸附效果的影响,确定最佳吸附条件:在常温下,吸附时间20min,pH=6.68的条件下用D206树脂吸附;Langmuir模型能够更好地拟合树脂吸附ClO-4的过程。研究表明:D206离子交换树脂吸附ClO-4时,离子交换过程的速度控制步骤为颗粒扩散控制。目前,国内外尚未有关于离子交换树脂吸附高氯酸盐的报道,本文为离子交换吸附高氯酸盐的理论研究和实际应用提供参考。
Through comparing several normal used ion exchange resin, the article screened an resin that deal with solution of ammonium perchlorate. It studied the impact of different test conditions on the absorption effect of the resin and determined the optimum condition witch is under the conditions of room temperature, adsorption time is 20min, value of pH is 6.68, ammonium perchlorate is absorbed D206 resin , Langmuir model can better fit the process of adsorption . Kinetics study shows that while D206 ion exchange resin absorbs C104- , the rate - determining step of ion exchange process is the particle diffusion control. Currently, there is no report about ion exchange resin adsorbing perehlorate yet, this article can provide reference for the theoretical research and practical application of ion exchange resin adsorbing perchlorate.
