摘要
本文考查介质pH、温度、吸附时间、树脂量等因素对树脂吸附过程的影响。实验结果表明:等温吸附服从Fre-undlich经验式,以lgQ对lgC作图,得一条直线,由直线斜率求得b=2.54,b值在2~10之间,表明树脂吸附镍的反应是容易进行的。测得吸附反应中树脂功能基与镍离子配位比为2∶1。
This article focuses on the effect on resin absorption of the facto rs such as pH of medium,temperature,absorption time, resin concentration,oscilla tions frequency etc.The result indicates that the interaction of Nickel being ab sorbed by resin is easy going. The complex ratio of the functional group to Ni i s approximately 2∶1.
