Ion exchange is a reversible exchange of ions between a solid ion exchanger and a liquid solution. The solid undergoes no structural change in the process. An ion exchanger, or ion exchange resin, can be a natural or synthetic substance which can...

Displacement of one ion by another. Cations and anions can be exchanged between a liquid and a solid exchange medium. Cation, or base exchange, can be used to soften a water. Cation and anion exchange are both used in preparation of boiler feed water...

The process of replacing one ion that is attached to a charged surface with another. A very important type of ion exchange is the exchange of cations bound to soil particles. Soil clay minerals and organic matter both have negative surface charges that...

Ion exchange is an exchange of ions between two electrolytes or between an electrolyte solution and a complex. In most cases the term is used to denote the processes of purification, separation, and decontamination of aqueous and other ion-containing...

Abstract This paper describes a study of the ion exchange properties of alginate fibers. The release of calcium ions into the contacting solution is measured by an atomic absorption spectrometer. The calcium alginate fibers are placed in aqueous solutions of Na^sub 2^SO^sub 4^;...

Commentary Ion Exchange The applications of ion exchange (IX) resins in gold metallurgy will be discussed in three main contexts. The first one focuses on the use of the IX resins for the concentration and recovery of gold from leach pulps or...
