A solid phase extraction procedure for Indium prior to its graphite furnace atomic absorption spectrometric determination

Phase equilibria in the solid state and colour properties of the CuO–In2O3 system

“…The compounds admixtured with copper(II) oxide or/and indium(III) oxide and the phases formed as a result of reactions of these oxides with other ones are known to be attractive materials for industry as components for production of electrodes, solar cells, liquid crystal displays, and other products [1][2][3][4][5]. The physicochemical properties and structures of CuO and In 2 O 3 are well known [6][7][8][9][10][11].…”

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

“…The highly selective bifunctional poly(VPA-co-GMAco-DVB) cation exchangers were synthesized by suspension polymerization [10,[11][12][13]. Table 1 and Figure 1 show the synthesis conditions, the polymerization scheme and the functionalization of the poly(VPA-co-GMAco-DVB) cation exchangers with iminodiacetic acid, respectively.…”

“…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].…”

“…However, the development of a highly selective ion exchanger is needed because the concentration of indium in seawater is low [8][9][10][11][12].…”

Simultaneous Preconcentration of Copper, Nickel, Cobalt and Lead Ions Prior to Their Flame Atomic Absorption Spectrometric Determination

“…Solid phase extraction procedures based on sorption of metal complexes on various support, such as silica gel, alumina and activated carbon in the two past centuries have been widely used for this purpose, among which activated carbon has been widely applied. The reasons for widespread application of the activated carbon as a trace collector for metal ion preconcentration [9][10][11][12][13][14][15][16] are strong interaction and quantitative adsorption of molecules with π electrons on activated carbon 17 . Because activated carbon is a type of hydrophobic adsorbent which adsorbs non-polar or little polar substances in aqueous solutions, metal ions to be preconcentrated need to be transformed in corresponding metal chelates [18][19][20][21] .…”
