title: Multiresidue determination of organophorous pesticides in camellia oil by matrix solid-phase dispersion followed by GC-FPD.
abstract: A novel analytical approach has been developed and evaluated for the quantitative analysis of 15 organophorous pesticides residues in camellia oils. The proposed methodology is based on acetonitrile/water (3:1, V/V) extraction, followed by matrix solid-phase dispersion, using aminopropyl as dispersant material. Then gas chromatography-flame photometric detection was applied for the pesticide residue analysis. The optimal sorbent quantity was studied. The results demonstrated that the method achieved acceptable quantitative recoveries of 71.5%-104.2% with relative standard deviations <19%, and the method limit of detection at or below the regulatory maximum residue limits for the pesticides were achieved.
