They can be categorised into various forms including
chelating resin, adsorbent resin, mixed bed resin, etc.

chelating resin," Journal of Hazardous Materials, vol.

chelating resin containing a salicylaldoxime group," Reactive and Functional Polymers, vol.
The synthesized resin was applied for adsorption of nickel (II) ions comparing with the conventional DTOF
chelating resin. The parameters affecting adsorption process as initial pH, agitation period, sorbent dosage, and initial concentration of Ni(II) ions were studied.
1989), or through capture of the positively charged unbound Al species on a cation-exchange or
chelating resin (e.g.
A buffered sample is loaded onto a column packed with an appropriate cation exchange
chelating resin. The anions pass through the column unretained while many of the cations are retained.

The
chelating resin preconcentration method has excellent analytical features of nonselective multielement determination for many trace elements in seawater, along with efficient removal of matrix elements such as Na, K, Ca, and Mg [5-10].
Similar results were obtained with previous study with
chelating resin (41).
In this work,
chelating resin was prepared by chemical attachment of the chelating moiety, 4-(2-pyridylazo)resorcinol(PAR) onto silica gel using an eco-friendly chemical transformation.
Adsorption is widely used, especially in the surface with a chelating moiety of the
chelating resin. During the past two decades, the use of
chelating resin for metal ion preconcentration and separation has been considerably increased [l-5].
