Separation of gallium and copper from hydrochloric acid by D2EHPA
Desalination and Water Treatment, 2015 AbstractSolvent extraction offers a better option for gallium recovery among many techniques. The liquid–liquid extraction of gallium(III)–copper(II) solution from hydrochloric acid medium using di-2-ethyl-hexylphosphoric acid (D2EHPA) in kerosene was studied. The effect of the reagent concentration and other parameters on the extraction of gallium(III)
