Application of Sol–Gel Hybrid Extraction Sorbent for Gas Chromatographic Analysis of Organophosphorus Pesticides

Sol–gel hybrid extraction sorbent based on methyltrimethoxysilane-cyanopropyltriethoxysilane (MTMOS-CNPrTEOS) was successfully synthesized by sol–gel process for use in solid-phase extraction (SPE) of organophosphorus pesticides (OPPs). Analysis was performed using gas chromatography–mass spectromet...
