Determination of Indium by Graphite Furnace Atomic Absorption Spectrometry after Coprecipitation with Chitosan

Adsorption Behavior of Cationic and Anionic Species on Chitosan Resins Possessing Amino Acid Moieties

“…Some researchers have applied chitosan to the separation and concentration of trace elements in water samples prior to trace analysis. [5][6][7][8][9][10][11][12][13][14][15][16][17][18] Chitosan as a base material for the development of a chelating resin and an ion-exchange resin is of great interest due to its advantages, such as easy derivatization of its amino group, and being more hydrophilic than synthetic base materials, like polystyrene-divinylbenzene, polyethylene, and polyurethane, which provides a fast sorption kinetic of ionic species in aquatic media. 8 Therefore, novel chitosan resins possessing chelating moieties have been developed by using a cross-linked chitosan resin as a base material.…”

On-line Determination of Zinc in Water and Biological Samples after Its Preconcentration onto Zincon Anchored Polyurethane Foam

“…There are several methods for the determination of zinc such as anodic stripping voltammetry, 1 spectrophotometry, 2 AAS, 3 FAAS, 4 GFAAS, 5 and ICP-MS. 6 These methods are of high sensitivity and accuracy. But some are expensive, timeconsuming, troublesome, and others are toxic.…”

Synthesis of Bifunctional Poly(Vinyl Phosphonic Acid-<i>co</i>-glycidyl Metacrylate-<i>co</i>-divinyl Benzene) Cation-Exchange Resin and Its Indium Adsorption

“…It is important to develop an adsorption and separation material with high selectivity. To separate indium from ITO waste fluid which is produced during the display etching process called "urban mining," the development of a selective adsorption and separation material for the recovery of indium from the etching waste fluid in highly acidic conditions is required [5][6][7].…”
