Studies on extraction of beryllium from thiocyanate solutions by quaternary ammonium halides

A 0.4 M tricaprylmethylammonium chloride solution in n-hexane was used for the quantitative extraction of beryllium from hydrochloric acid (pH 3) and 5 M potassium thiocyanate. Beryllium was stripped from the organic phase with 1 M sodium hydroxide, then determined volumetrically with bismuthyl perc...

Description
Summary:A 0.4 M tricaprylmethylammonium chloride solution in n-hexane was used for the quantitative extraction of beryllium from hydrochloric acid (pH 3) and 5 M potassium thiocyanate. Beryllium was stripped from the organic phase with 1 M sodium hydroxide, then determined volumetrically with bismuthyl perchlorate and bromocresol green indicator. Beryllium was extracted in presence of a large number of elements which are usually associated with it in beryl and in fission products of nuclear fuel.
