摘要：A systematic method for analysis of dieldrin, Eulan U-33, Mitin LA, and Mitin FF from wool fabrics, which are being used as the main mothproofing agents in Japan, was established. It was found that Eulan U-33, Mitin LA and Mitin FF are quantitatively extracted with ether from the 10% NaOH solution of wool fabrics, but further extraction with hexane is necessary for dieldrin. Dieldrin and Eulan U-33 were determined by injecting the extract into the electron capture detection gas chromatograph (ECD-GC) fitted with 2% OV-1 column. The extract was divided into two equal parts, the solvent was evaporated to dryness, and the residues were used to determine Mitin LA and Mitin FF. One of them was reacted with dimethyl sulfate in a basic medium and the resulting N-methyl compounds were determined by ECD-GC on 2% OV-1 column. The other was hydrolyzed with 10% NaOH under reflux and the resulting 3, 4-dichloroaniline was determined as its trifluoroacetamide by ECD-GC on 1% PEG-20 M column. The limits of determination were as follows : dieldrin, 0.02 μg/g ; Eulan U-33, 1 μg/g ; Mitin LA, 0.5 μg/g ; Mitin FF, 0.5 μg/g. The content of these mothproofing agents in 48 commercial wool products was determined.
