an·i·on ex·chang·er

(an'ī-on eks-chānj'ĕr),
An insoluble solid, usually a polystyrene or a polysaccharide, with cation groups (for example, -NR3+ or -NR2H+), which can attract and hold anions that pass by in a moving solution in exchange for anions previously held.

ion exchanger

n.
A polymer containing charged groups to which other charged mobile ions become attached or replaced, used in chromatography.

We investigated the impedance of the porous ion exchanger with various inorganic ions such as [Ca.sup.2+], [Na.sup.+], S[O.sub.4.sup.2-], [Cl.sup.-].
It is clear from this table that the ratio of anionic part represented by vanadate and tungstate ions in the ion exchanger is higher than that of cationic part represented by zirconium ions; this result confirms that the anionic part in the prepared ion exchange material is responsible for the ion exchange process inside the ion exchanger rather than the cationic part [17].
In general, the ion exchanger adsorbs counter ions of the ion exchange group.
The increase in the removal capacity is found to be in the order of the corresponding PZC values of the hybrid ion exchangers. Further it is suggested that the higher exchange capacity is the result of Donnan effect and specific adsorption of chromium by the oxides / hydroxides present inside the matrix of the organic cation exchanger.

However, the Chelating Resins Market have exact same polymer matrix and bead form as those of conventional ion exchangers. Request TOC of this Report- https://www.factmr.com/connectus/sample?flag=T&rep_id=594 Sulfonic acid and the conventional ion-exchange resins are extensively used in several industrial applications such as recovery and creation of metals, industrial wastewater treatment.
For the production of soft water, more and more ion exchangers with sodium chloride regeneration have been used for more than 50 years.
(2001), these elements are efficient ion exchangers for the removal of heavy metals from aqueous solutions.
Recovering even small amounts of metal Traditionally, metal ions are removed from solutions with the help of chemical coagulants or ion exchangers, which usually require adjustments to the solution's pH or significant extra energy in order to function efficiently.
Ion exchangers are the older and somewhat less sophisticated technology.
Union Showa also manufactures and develops various Ion Exchangers at its Yokkaichi Plant, Mie Prefecture for nuclear waste remediation.
