The present study describes the synthesis, characterization and application of two mesoporous silica material based coated magnetic nanoparticles namely Fe3O4 -SBA-15 and Fe3O4 -MCM-41 for the simultaneous preconcentration of three selected organophosphorus pesticides (OPPs) namely chlorpyrifos, diazinon and parathion methyl from water samples. The resultant sorbent material was physicochemically and morphologically characterized by field emission scanning electron microscopy (FESEM), X-ray diffraction (XRD) and N2 adsorption analysis. OPPs pesticides extraction efficiency of two sorbents were evaluated through magnetic solid phase extraction (MSPE) using high performance liquid chromatography with ultraviolet detector (HPLC/UV). The main parameters affecting the sorbent efficiency namely extraction time and desorption solvent were optimized. Comparatively, Fe3O4 -SBA-15 achieved excellent percent recovery (97.5%) compared to the Fe3O4 -MCM-41 (87.1%) under optimum condition respectively. The result appealed that the Fe3O4 -SBA-15 composite was efficient sorbent with good capability for the preconcentration of selected OPPs from water samples.AThe present study describes the synthesis, characterization and application of two mesoporous silica material based coated magnetic nanoparticles namely Fe3O4 -SBA-15 and Fe3O4 -MCM-41 for the simultaneous preconcentration of three selected organophosphorus pesticides (OPPs) namely chlorpyrifos, diazinon and parathion methyl from water samples.
