Abstract

A simple method was developed for separation of bromine from metallic selenium. This method enables easy preparation of⁷⁷Br by proton bombardment of metallic selenium (enriched⁷⁷Se or⁷⁸Se). The method consists of heating the metallic selenium with H₂O to 300°C in a small autoclave for about three hours. The⁷⁷Br is distilled from the obtained solution after the addition of H₂SO₄+K₂Cr₂O₇. The step also removes the arsenic produced together with the selenium.
