离子交换树脂法去除PIA废水中Co^(2+)、Mn^(2+)的研究

Study of the Removal of Co^(2+)and Mn^(2+)from PIA Wastewater by Using Ion Exchange Resin Method

研究了D001、D113、116三种离子交换树脂法去除精间苯二甲酸(PIA)废水中的Co2+、Mn2+时的交换性能和再生性能,结果表明:三种树脂均可有效去除废水中的Co2+、Mn2+,相同体积的湿树脂交换Co2+、Mn2+总量大小为D113>116>D001,再生后交换性能可恢复。

This article studies the exchange and regeneration performance of the removal of Co^2＋ and Mn^2＋ from PIA wastewater by using D001 ,Dl13 and 116 resin. The results show that all the three kinds of resins can effectively remove Co^2＋ and Mn^2＋ in wastewater,the Co^2＋ and Mn^2＋ exchange capacity of the resins which have the same volume is D113 ） 116 〉 D001, and the exchange performance can be recovered after regeneration.
