フルボ酸溶液の塩素処理によって生成する有機塩素化合物のGC/MS 分析

The main precursor of chlorinated organic compounds formed during chlorination process of drinking water are humic substances. Fulvic acid in treated sewage and that in leaf mold extract were chlorinated, and the generated non-volatile compounds were analyzed by GC/MS following methylation with methanol and sulfuric acid.Chloroacetic, chloropropionic, chloromaleic, and chlorofumalic acids were identified, and the generation of chlorinated compounds having ring structure such as aromatic ring was suggested for the chlorination of fulvic acid in treated sewage.Chloroacetic, chloropropionic, chloromaleic, and chlorofumalic acids were identified in the chlorination products of fulvic acid in leaf mold, but the formation of chlorinated compounds having ring structure was not suggested.
