LIQUID-LIQUID EXTRACTION OF GALLIUM(III) FROM HYDROCHLORIC ACID SOLUTIONS BY ORGANOPHOSPHORUS COMPOUNDS AND HIGH-MOLECULAR WEIGHT AMINES

Abstract
The extraction of gallium(III) from hydrochloric acid solutions has been investigated using organophosphorous compounds (Tributylphosphate, trioctylphosphine oxide and di-(2-ethylhexyl)-phosphoric acid) and high-molecular weight amines (Trioctylamine and trioctylmethylammonium chloride). The equilibrium expressions are proposed on the basis of the distribution data.
