The recovery of trace elements after the oxidation of organic material with 50 per cent. Hydrogen peroxide

Abstract

The recovery of several elements, at the p.p.m. level, from various organic materials after oxidation with sulphuric acid and 50 per cent. hydrogen peroxide has been studied. Most of the elements investigated could be recovered quantitatively, but germanium, arsenic, selenium and ruthenium suffered losses under some or all of the conditions examined. The causes of these losses are discussed.
