离子交换树脂在ECP-2工艺加工药液回收处理中的运用

The Application of Ion Exchanger Resins in ECP-2 Solution Recycle

电影洗印厂大量的废水和废液的排放,会造成严重的环境污染。保护生态环境,是我们每个生活在这个地球上人的共同责任。为了解决这个问题,洗印厂将彩色显影液和停显液经过回收处理再循环使用,从废液中提取CD2的含量,这对环保和经济上都是有益的。本文从使用离子交换树脂的原理、阴离子交换树脂净化彩色显影液、阳离子交换树脂净化停显液、停显液里CD2含量的分析方法和离子交换树脂的运用作了较详细的叙述。

The large amount of waste water and waste solution produced by film processing plant could cause serious environment pollution. Living on the earth, it is our common responsibility to protect our natural environment. To solve the issue, the film processing plant is working hard to recycle color developing solution and stop bath and recover CD2 developing agent from waste solution, which is beneficial economically as well as in environmental protection. The principles and application of ion exchanger resins, color developing solution purification by anion ion exchanger resins, stop bath purification by cation ion exchanger resins and analysis of CD2 amount in stop bath were described in detail.
