In the present work, a potential solid-phase extraction (SPE) material based on graphene anchored with platinum nanoparticles (Pt-Graphene) was prepared and characterized by scanning electron micrographs and transmission electron micrograph. The carbamates residues in fish were enriched by SPE filled with Pt-Graphene and detected by ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). The proposed extraction protocol exhibited satisfactory recoveries (76.5-115.6%), low limit of quantitation values in μg kg -1 level, and good precision for the studied ten carbamates. These results demonstrated the feasibility of the proposed protocol. The developed Pt-Graphene nanoparticles showed excellent performance for extracting analytes at trace levels, indicating that it could be used as a potential SPE sorbent in food residue analysis.
