概要

論文の詳細を見る
A method for the simultanious micro-determinations of halogens and sulfur in organic substances is described.<BR>Sample is burned in an oxygen stream contacting with a platinum catalyst, and halogen and sulfur dioxide formed are quantitatively absorbed on the silver gauze packed in an absoption funnel. A weight gain of the silver gauze representes the amout of halogen and sulfur tetraoxide.<BR>Subsequently, the silver gauze is electrolyzed in a known volume of solution of sulfuric acid, of which the concentration has previously been determined, and sulfate ion extracted from the silver gauze is determined by EDTA titration.
