Ion Exchange and the Swelling of Ion-exchange Resins

Russian Chemical Reviews, 1969
The review deals with the modern hypotheses concerning the physicochemical properties of ion-exchange resins and their effects in the interaction between resins and solvents and solutes, mainly electrolytes. The problems associated with the permeability of resins, the steric accessibility of the functional centres, and their screening are discussed ...

Adsorption of lanthanum and cerium on chelating ion exchange resins: kinetic and thermodynamic studies

Separation Science and Technology, 2021
As the demand for rare earth elements (REE) increases in the coming years, techniques to obtain these elements from different sources may be explored. A hydrometallurgical route may achieve the sustainable approaches signed by countries.

Adsorption kinetics and isotherms for the removal of nickel ions from aqueous solutions by an ion-exchange resin: application of two and three parameter isotherm models

, 2016
The capacity of a strong cation-exchange resin for removal of nickel from aqueous solutions was investigated under different conditions such as contact time, initial nickel ion concentration, stirring speeds, solution pH, and resin dose.

Removal of copper(II) ions from synthetic electroplating rinse water using polyethyleneimine modified ion-exchange resin

, 2016
Removal of copper ions (Cu(II)) from synthetic electroplating rinse water (SEPRW) by using modified ion-exchange resin was investigated. Modification of the cationic exchange resin was carried out by impregnating polyethyleneimine (PEI). Impregnation was

Diffusion in ion exchange resins

AIChE Journal, 1963
AbstractObservations on the rate of ion exchange in Dowex 50W resins are reported. These measurements were made under conditions where solid diffusion was the governing phenomenon for six pairs of ions sodium‐zinc, sodium‐silver, silver‐aluminum, zinc‐copper, zinc‐aluminum, and aluminum‐cerium (trivalent).

Radium-226 Removal from Simulated Produced Water Using Natural Zeolite and Ion-Exchange Resin

, 2016
Large volumes of produced water with high dissolved solids content are generated by the oil and gas industry. The presence of naturally occurring radioactive materials (NORM), such as radium, in this flowback water adds to the costs associated with its ...

Aminovinylpyridine ion-exchange resins

Russian Journal of Applied Chemistry, 2006
Highly permeable aminovinylpyridine ion-exchange resins are synthesized by the reaction of epoxy/polyvinylpyridine prepolymers with aliphatic amines. Synthetic conditions are optimized and physicochemical and sorption characteristics of the resulting polyelectrolytes are examined.

Glucose dehydration to 5-hydroxymethylfurfural in ionic liquid over Cr3+-modified ion exchange resin

, 2015
In this work, D001-cc cation-exchange resin was modified by CrCl3 using an ion exchange method to obtain a Cr3+-D001-cc catalyst. FT-IR, UV-vis, SEM, EDX, ICP-OES and Py-IR were used to characterize the catalyst. Subsequently, the effects of the modified
