Abstract: | A method has been derived for the selective extraction of antimony(V) from hydrochloric acid solution with ethyl acetate. The method can be employed for the rapid determination of antimony in antimonates of lead, tin, mercury, nickel and chromium and in type metal. Iron(III), cobalt(II) cadmium(II), and large amounts of copper(II) and tin(II) interfere with the extraction. For the analysis of type metal, tin must be oxidized to the tetravalent state. |
