Liquid-Liquid Extraction of Gallium from Jajarm Bayer Process Liquor Using Kelex 100
The solvent extraction of gallium from a concentrated Jajarm Bayer process liquor containing 164.90 g/l of Na2O, 86.70 g/l of Al2O3 and 106.02 ppm of gallium was investigated using 10 vol.% Kelex100, a 7-alkyl substituted-8 hydroxyquinoline as an extractant, 10 vol.% etanol as a modifier and kerosene as a diluent. At (Vo :Va = 1.0:1.0) ...

متن کاملSolid-phase extraction of gallium(III) with hydrophobic 8-quinolinol derivatives-impregnated resin from aqueous acidic and alkaline solutions.
Solid-phase extraction (SPE) of gallium(III) with hydrophobic 8-quinolinol derivatives (HQs)-impregnated resin from aqueous acidic and alkaline solutions has been investigated. The HQs used were 7-(4-ethyl-1-methyloctyl)-8-quinolinol (HEMOQ), 5-octyloxymethyl-8-quinolinol (HO(8)Q), 2-methyl-5-octyloxymethyl-8-quinolinol (HMO(8)Q), 5-dioctylaminomethyl-8-quinolinol (HN(8)Q), 7-bromo-5-octyloxyme...
متن کاملExtraction of bismuth(III) with 2-bromoalkanoic acid in nondonating solvent from highly acidic aqueous solution.
The extraction behaviors of bismuth(III) with carboxylic acid (HL), which have not yet been clearly elucidated, because of the precipitation of hydroxide, were studied using the 2-bromoalkanoic acid in benzene and in hexane systems under aqueous conditions of high acidity at I = 1.0 M ((H,Li)NO3). The extraction equilibria were analyzed based on the-initial concentration of nitric acid and the ...
متن کاملSolvent Extraction Of Chromium (VI) From Aqueous
The extraction of chromium (VI) from hydrochloric, hydrobromic, and acetic acid solutions with Tri caprylamine oxide (TCAO) in benzene has been studied. The extractions from hydrochloric and hydrobromic, acid solutions are nearly quantitative and are partial from acetic acid solutions. The optimum conditions for extraction were established from the study of the effect of several variables like–...
