一、前言作者等为了解决阴离子交换柱(固定床)的设计问题,进行了“交换区法”在阴离子交换体系中应用的研究。离子交换柱工作时的典型状态如图1所示,即最上部为饱和区(或称耗尽区),中部是交换区(交换作用在这区中进行),下部为原型区(即树脂还未进行交换,仍保持原来的型式) 为了设计上的需要,曾有人企图通过数学处理来描述柱工作状态及其变化规律,例如应用简单的吸附过程概念、基于质量作用的动力学概念等等。但由于数学处理上的困难(后者还加上活度数据的缺乏)。因之,未能得到满意的结果。
I. INTRODUCTION In order to solve the design problem of anion exchange column (fixed bed), the author of the preface made a study on the application of “Exchange Zone Method” in anion exchange system. Ion exchange column when the work of the typical state shown in Figure 1, that is, the uppermost part of the saturation zone (or depletion zone), the middle is the exchange zone (exchange in this area), the lower part of the prototype area For the sake of design, some people tried to describe the working state of column and its variation through mathematical processing, such as the concept of simple adsorption process, the concept of dynamic based on mass effect, and so on. However, due to mathematical processing difficulties (the latter plus the lack of activity data). As a result, failed to get satisfactory results.
