TLDR
In this article, a method for quantitative extraction of arsenic, antimony, and bismuth with potassium ethyl xanthate-carbon tetrachloride was described, and the effect of acidity, reagent concentration, period of extraction and diverse ions were discussed.Abstract:
Methods are described for quantitative extraction of arsenic(III), antimony(III) and bismuth(III) with potassium ethyl xanthate-carbon tetrachloride. The optimum acidity conditions are 0.1–0.2 M hydrochloric acid for arsenic, 1.8–2.5 M hydrochloric acid for antimony and pH 1.5–4.0 for bismuth. From the organic extracts arsenic and antimony are estimated by conventional iodometric methods while bismuth is determined spectrophotometrically at 400 nm. The effect of acidity, reagent concentration, period of extraction and diverse ions are discussed. The infra-red spectra are also described.read more

Determination of antimony in concentrates, ores and non-ferrous materials by atomic-absorption spectrophotometry after iron-lanthanum collection, or by the iodide method after further xanthate extraction.
TL;DR: In the spectrophotometric iodide method, the importance of the preliminary oxidation of all of the antimony to antimony(V), to avoid the formation of an unreactive species, is shown.
