An extraction study of gallium, indium, and zinc with mixtures of sec-octylphenoxyacetic acid and primary amine N1923

4-Methyl-N-n-Octylaniline as a New Liquid Anion Exchanger for the LiquidLiquid Extraction of Gallium (III): Application to Electronic Waste LED

“…The method for the extraction of gallium (III) with LIX26 (alkyl substituted 8-hydroxyquinoline) in n-decanol as modifier and kerosene as diluent was studied along with thermodynamic functions ΔH ΔS and ΔG 12 A synergistic extraction systems consisting of sec-octylphenoxy acetic acid and primary amine N1923 have been studied for selective extraction between Ga/In and Zn. 13 Organophosphorous reagent also plays important role in the solvent extraction of Ga (III). Some of the examples are D2EHPA (Di-2-ethylphosphoric acid) 16 Extractability of long chain amines has been studied for solvent extraction of many heavy metals and rare earths.…”

“…Effect of amine structure on gallium extraction from strong acid hydrochloric acid solution has been investigated. The degree of extractability of extractants was arranged in the order Adogen-464 > TABAC > TOA, Hostarex A-327, Adogen-364, Hostarex A-324 > THPA > benzyldimethylalkylammonium chloride > THA > HOEF 2562, Adogen 283 26 .The use of high molecular weight amine extractants including Adogen-464 27 , Aliquot-336S 28 , Tris(2-hydroxy-3,5-dimethylbenzylamine 29 ,n-octylaniline 30 , Nn-octylaniline 31 , 2-octylaminopyridine 32 , primary amine N1923 13 have been reported in the literature for liquid-liquid extraction of gallium. Seeing this considerable practical and historic interest in the system containing high molecular weight amines as liquid anion exchanger for extraction of Ga(III) , 4-Methyl-N-n-octylaniline is introduced as new analytical reagent for solvent extraction of Ga(III).…”

Selective extraction of In(III), Ga(III) and Zn(II) using a novel extractant with phenylphosphinic acid

“…A large number of extractants for In(III) and Ga(III) have been reported, including phosphoric acids [1][2][3][4][5][6][7], phosphinic acids [8][9][10], oximes [11], carboxyl acids [12], and amines [13]. In addition, the synergistic extraction of In(III) and Ga(III) have been reported using trialkyl amine, 3,5-dicholorophenol and primary amine as the synergists [14][15][16]. However, there are some problems, for example, the extraction equilibrium A C C E P T E D M A N U S C R I P T…”

Selective Extraction of Ga(III) with <i>p-t</i>-Butylcalix[4]arene Tetrahydroxamic Acid

“…Methyl isobutyl ketone (MIBK) [6], carboxylic acids [7,8], amines [9][10][11], quinolines [12] and β-diketones [13] have also been applied for this goal. In addition to these compounds, hydroxamic acids [14] are a class of versatile extractants which have significant importance as analytical tools for the separation and quantitative determination of a large number of metal ions [15,16].…”
