Abstract: |
A high performance liquid chromatographic(HPLC)method was established for the simultaneous separation and determination of α-bromocinnamaldehyde(α-BCA),thiabendazole(TBI),triclosan(TCC) and triclocarban(TCS) in textiles.The samples were dissolved with ethyl acetate and extracted by ultrasonic extraction.The extract was concentrated and filtrated,then the separation of analytes was preformed on a symmetry C18(4.6 mm i.d.×250 mm,5 μm) column,with methanol-tetrahydrofuran-20 mmol/L NH4Ac as mobile phase(60∶20∶20) using isocratic elution at a flow rate of 0.8 mL/min.The photodiode array detector was set at 230,260,300 nm.The results indicated that four substances were completely separated in 15 min.The calibration curves showed good linearities in the ranges of 0.2-100 mg/L for α-BCA and TBI,0.1-100 mg/L for TCC,and 0.3-100 mg/L for TCS,with correlation coefficients of 0.998 8-0.999 9.The recoveries of four substances were in the range of 80.5%-104.9%,with RSDs below 7.2%.The quantitation limits for α-BCA,TBI,TCC,TCS(LOQ,S/N≥10) in three kinds of textiles were in the ranges of 0.2-0.5,0.2-0.4,0.1-0.2,0.3-0.6 mg/kg,respectively.This method was simple,rapid and sensitive,and was applied in the determination of organic antibacterial and antifungal agents in textiles with satisfactory results. |
