Determination of Triclosan in Textiles by Spectrophotometry

A spectrophotometric method was established to determine the content of triclosan in textiles.Triclosan in textiles was ultrasonically extracted with dichloromethane as the extraction solvent,then the wavelength of the extraction solution was set at 282nm.The linear correlation,precision,recovery and detection limit of the method were studied.A good linear relationship was obtained in the range from 0.2 to 80mg/L with correlation coefficient of 0.9998.The recovery ranged from 91.15% to 103.51% and the RSDs were all less than 5%.The detection limit was 0.1mg/L at the condition of S/N(signal/noise)=3.
