一、前言早在1952年,Michaels通过阳离子交换实验提出了“交换区”的概念,并建立了一种比较简易地测定交换区高度的方法,从而可以只需通过一些小规模的实验,即可进行柱的设计。之后庄人杰等把交换区的概念应用于阴离子交换树脂,对溶液流速、溶液浓度、
I. INTRODUCTION As early as 1952, Michaels proposed the concept of “exchange zone” through cation exchange experiments and established a simpler method of determining the height of the exchange zone so that it would be possible to pass only a few small experiments Column design. Zhuang Renjie after the concept of the exchange zone applied to the anion exchange resin, the solution flow rate, solution concentration,
