Research on Adsorption Performance of P204 Solvent Impregnated Resins for Gallium(Ⅲ)in Sulfuric Acid Solution AITranslate
Abstract AITranslate
P204 solvent impregnated resins(P204 SIRs)were prepared by using styrene-divinylbenzene macroporous resin(HZ818)as a carrier and bis(2-ethylhexyl)phosphoric acid(P204)as an extractant,and were characterized by scanning electron microscope(SEM),infrared spectrometer(IR),and thermogravimetric analyzer(TG)to investigate the adsorption performance of P204 SIRs for Ga(Ⅲ)in sulfuric acid solution.The results show that the optimal pH value for Ga(Ⅲ)adsorption by P204 SIRs is 1.8.The adsorption equilibrium time of Ga(Ⅲ)at 298 K is approximately 20 h,with a saturation adsorption capacity of 10.9 mg/g,and the kinetic adsorption behavior could be described by a pseudo-second-order kinetic equation as t/Qt=0.2173+0.0962t.The isothermal adsorption of Ga(Ⅲ)by P204 SIRs follows the Langmuir isothermal adsorption model of Ce/Qe=0.4482+0.0588Ce,and the fitted saturation adsorption capacity of Ga(Ⅲ)at 298 K is about 17 mg/g.
