ABSTRACTAn efficient, novel and green Graphene Oxide-Poly-L-Lysine (GO-PLL) adsorbent was successfully synthesised used for solid-phase extraction of aflatoxin M1 (AFM1) in liquid milk samples followed by high performance chromatography (HPLC) equipped with fluorescence detector (FLD). The characterised Fourier Transform Infrared Spectrophotometry (FT-IR), Field Emission Scanning Electron Microscopy (FESEM), Energy-dispersive X-ray spectroscopy (EDX) X-Ray diffraction (XRD) analysis. Different parameters affecting the recovery percentage AFM1 including pH sample solution, amounts adsorbent, contact time desorbent solution (types volume) were completely investigated optimised. It found that, an enrichment factor 15.2, calibration curve is linear range 0.05–4.00 ng ml−1 limit detection (LOD) quantification (LOQ) values 0.019 0.063 mL−1, respectively. relative standard deviations (RSDs) ranged from 4.5% to 5.7% 4.2% 6.7% intra-day inter-day variations, Finally, proposed method applied determination trace levels different samples.KEYWORDS: Aflatoxin M1Graphene adsorbentHPLCmilk AcknowledgmentsThe authors wish thank University Neyshabur financial support this project (grant number: 14703).Disclosure statementNo potential conflict interest reported author(s).Additional informationFundingThis work supported Medical Sciences [grant number:14703].
