Abstract

The simultaneous determination of chlorine or bromine together with carbon and hydrogen in highly halogenated organic compounds was achieved by dry-oxidation of the sample with oxygen either in an empty or packed combustion tube. The carbon dioxide and water produced were absorbed in the usual way in soda-asbestos and anhydrone. The halogen was absorbed on a silver gauze roll kept at 550 °C, placed in a specially-designed silica absorption tube, connected externally between the combustion and water absorption tubes, and determined gravimetrically. The method is simple, rapid, and accurate.
