ABSTRACT
Solid-phase microextraction (SPME) coupled to gas chromatography (GC) has been developed for the analysis of naphthalene residues in five textiles samples using sol-gel-derived 5,11,17,23-tetra-tert-butyl-25,27-dihydroxy-26,28-diglycidyloxycalix[4]arene/hydroxy-terminated silicone oil fiber. The main parameters affecting extraction and desorption process such as temperature and time were optimized statistically. Compared with four commercial stationary phases and sol-gel-derived OH-TSO SPME fiber, this fiber showed statistically highest enrichment capability for naphthalene in the textile sample. SPME–GC–flame ionization detection method showed good linearity for the tested concentration range with regression coefficient being 0.9996. Detection limits was 1.17 ng/g. Relative standard deviations (n= 6) of method at three concentration levels of 1.0, 0.5, and 0.1 μg/g ranged between 1.1% and 5.4%, which provided good analytical precision. In addition, this fiber had satisfying fiber to fiber and batch to batch reproducibility. Recoveries for the analyte ranged from 78.3% to 102.7%. It indicated that this method developed was an efficient and accurate procedure for determination of naphthalene residues in textiles samples.
