Abstract: | Antimony(III) can be extracted rapidly and quantitatively into benzene from a 10 M H2SO4–0.03 M HBr system. The extracted antimony bromide has an antimony to bromine ratio of 1:3. Under the above optimum conditions for extraction of antimony, the behaviour of 35 other elements was studied; As3+, Ge4+, Se4+, and Sn2+ were extracted almost quantitatively, and the percentage extraction of Hg2+, Bi3+, and Te4+ was 74.1%, 10% and 5.5% respectively. The extraction of the elements into benzene from a 5 M H2SO4–0.01 M KI system was also investigated, A comparison of the two systems is given. |
