In this paper, a simple, rapid, solvent-less and environmental friendliness microextraction method, microwave-assisted extraction-hollow fiber-liquid/solid phase microextraction (MAE-HF-L/SME), was developed for simultaneous extraction and enrichment of 54 trace hydrophilic/lipophilic pharmaceutical and personal care products (PPCPs) from fish samples. A solid-phase extraction material, solid-phase microextraction (SPME) fiber, was synthesized. The SPME fiber had a homogeneous, loose structure and good mechanical properties, and they exhibited a good adsorption capacity for most PPCPs selected. The material formed the basis for the method of MAE-HF-L/SME. A method of liquid chromatography-high resolution mass spectroscopy (LC-HRMS) for analysis of 54 PPCPs. Under optimal synthesis and extraction conditions, the limits of detection (LODs, n = 3) and the limits of quantitation (LOQs, n = 10) for the 54 PPCPs were between 0.01-0.50 mu g.kg(-1) and 0.052.00 mu g.kg(-1), respectively. Percent recoveries and the relative standard deviations (RSDs) in spiked fish samples (n = 6) were between 56.3%-119.9% and 0.3%-17.1%, respectively. The microextraction process of 54 PPCP5 in MAE-HF-L/SME took approximately 12 min. The method has a low matrix interference and high enrichment factor and may be applicable for determination of 54 different PPCPs in fish samples. (C) 2017 Elsevier B.V. All rights reserved.
