Separation of copper and zinc by ion exchange resins

Removal of Copper from Aqueous Solution by Ion Exchange Resins

[Ion exchange resins].

Ion exchange resins have been used to help formulate pharmaceuticals since the late 1950's. During that time they have proved to be safe and effective excipients and are now used in many commercial formulations throughout the world. In this article we will look at some of the common problems faced by formulators and how using ion exchange resins may be able to solve them. Ion exchange resins ar...

Displacement chromatography on synthetic ion-exchange resins. 1. Separation of organic bases and amino-acids using cation-exchange resins.

9. Accumulation of glutamate also occurred in isolated kidney cortex, spleen, lung and chorion. Six other tissues examined maintained a concentration gradient between tissue and medium, but did not increase the glutamate concentration above the original level. 10. It is pointed out that tissue slices afford a system in which problems of permeability and storage can be studied under controlled c...

Copper(II) Removal using Three Cation Exchange Resins: Ion Exchange Equilibrium and Kinetics

The removal of copper from aqueous solution by Amberjet 1500H, Amberjet 1300H and Amberlite IRC86 ion exchange resins is described. The Amberjet 1500H shows a remarkable increase in sorption capacity for copper compared to other adsorbents. The adsorption process shows maximum removal of copper in pure aqueous solution for an initial copper concentration of 5.98 mmol/L. The metal ions adsorptio...
