Abstract
A simple and efficient hollow fiber-based method, namely magnetic solvent bar liquid-phase microextraction (MSB-LPME) combined with gas chromatography-flame ionization detection (GC-FID) has been successfully developed for the sensitive determination of selected phthalate esters (PEs) in environmental water samples. The analytes were extracted from sample solution to the organic solvent immobilized in a fiber. Following the extraction, the analyte-adsorbed magnetic solvent bar can be easily isolated from the sample solution by a magnet which could greatly simplify the operation and also reduce the total pretreatment time. The bar was primarily eluted with methanol, evaporated to dryness while the residue was dissolved in toluene and finally injected into GC-FID. Begin with, effective parameters controlling the performance of the microextraction were evaluated and optimized. The values of the detection limit of the method were in the range of 0.02-0.09 µg L-1 and the RSD% values for the analysis of 25.0 g µL-1 of the analytes was below than 6.0% (n = 7). A worthy linearity (0.996 ≥ r2 ≥ 0.993) and a broad linear range (0.2-250 µg L-1) were achieved. The method was finally employed for the preconcentration and determination of the PEs in environmental water samples and satisfactory results were obtained.
