- 論文の詳細を見る
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 (HO8Q), 2-methyl-5-octyloxymethyl-8-quinolinol (HMO8Q), 5-dioctylaminomethyl-8-quinolinol (HN8Q), 7-bromo-5-octyloxymethyl-8-quinolinol (HBrO8Q), and 5-(2-ethylhexyloxymethyl)-8-quinolinol (HOEHQ). Various factors affecting the SPE, such as the substituents of the HQs, HCl and NaOH concentrations in the aqueous phase, the HQ concentration in the resin, and the equilibration time were clarified. The extractability for gallium(III) from the aqueous solution became higher in the following order: HBrO8Q < HEMOQ < HO8Q < HN8Q < HMO8Q at 3 mol l-1 HCl; HMO8Q < HO8Q < HOEHQ < HEMOQ < HN8Q < HBrO8Q at pH 0.4; HMO8Q < HO8Q 竕・HOEHQ < HN8Q < HEMOQ at 3 mol l-1 NaOH.
