Methods for the qualitative analysis and determination of antimicrobial agents in fabrics are described. At present, antimicrobial agents mainly used are 2,4,4'-trichloro-2'-hydroxydiphenyl ether (Irgasan DP300), 3-(trimethoxysilyl) propyldimethyloctadecyl ammonium chloride (DC5700) and thiabendazole (TBZ). The procedure of qualitative analysis is as follows : (1) DC-5700 in fabrics is checked by the adsorption of bromophenol blue (BPB) on the strips packed in column. (2) Irgasan DP300 eluted with ether from fabrics is detected by Gibbs reagent on silica gel thin layer chromatography (TLC). (3) TBZ is eluted with methanol from the fabrics after the ether-elution and detected by UV 254 nm after spraying sulfuric acid on silica gel TLC. DC-5700 is determined from the amount of 1-octadecene, formed in Hofmann degradation, measured by gas-liquid chromatography (GLC). The determination of Irgasan DP300 in fabrics is carried out by high performance liquid chromatography (HPLC) on the acidic fraction of extract with methanol : acetic acid (9 : 1) under reflux and TBZ is determined by GLC on the alkaline fraction of the abovementioned extract. By using the qualitative and quantitative system, Irgasan DP300,DC-5700 and TBZ were detected in 12,4 and 2 samples, respectively, of 23 commercial fabrics treated with antimicrobial agents.
