Determination of triclosan in textiles by solid phase extraction-high performance liquid chromatography

An effective method for determination of triclosan in textiles by solid phase extraction- high performance liquid chromatography was developed. The samples were ultrasonic extracted,and then cleaned and enriched by a Sep-Pak Vac Silica solid phase extraction( SPE) cartridge. The separation was performed in a Kromasil C18 column( 250 mm × 4. 6 mm i. d.,5 μm) by using the mobile phase consisting of H2O / CH3CN( 15 /85,V / V). Detection was performed at 280 nm by extenal standard method. The result of experiment shows that calibration curve of triclosan was linear within the range of 0. 05- 20. 0 mg / kg,the limit of detection was found to be 0. 01 mg / kg,and the limit of quantification, 0. 05 mg / kg. The extraction recoveries were between 94. 0% and 100. 4% and the RSDs were 2. 0%- 4. 4%.
