Science Letters:A new configuration of membrane stack for retrieval of nickel absorbed in resins

Abstract： A new configuration integrated ion exchange effect with both electro-migration and electrochemical reaction in a single cell was developed to effectively retrieve metal ions from simulated wastewater using ion exchange resins without additive chemicals. By simply assembling cation exchange resins and anion exchange resins separated by homogeneous membranes, we found that the system will always be acidic in the concentrate compartment so that ion exchange resins could be in-situ regenerated without hydroxide precipitation. Such a realizable design will be really suitable for wastewater purification. 作 者： CHEN Xue-fen    WU Zu-cheng   作者單位： Department of Environmental Engineering, Zhejiang University, Hangzhou 310027, China  期 刊： 浙江大學(xué)學(xué)報B（英文版）  SCI   Journal： JOURNAL OF ZHEJIANG UNIVERSITY SCIENCE B  年，卷(期)： 2005, 6(6)  分類號： X703.1  Keywords： Nickel    Ion exchange resin    Electro-migration    Electrochemical
