Abstract

A highly accurate method for measuring pentachlorophenol (PCP) concentrations in textile samples was developed. This highly accurate method for the analysis of textile samples is valuable, given the inherent challenges associated with the complexity of the sample matrix. This method can be applied to certify the concentration of pentachlorophenol in textile CRMs. A measurement procedure based on isotope dilution liquid chromatography‐isotope dilution mass spectrometry (LC‐IDMS) was developed. Samples were pretreated with acid and then with n‐hexane. Excellent precision was obtained. The validated concentration ranges for the method were 1.0–50 ng/g, the LOD was 1.0 ng/g, and the LOQ was 5.0 ng/g. The precision of this method is in the range of 0.80–1.40%. The method can trace to mass.
