Description
Summary:•Melamine sponge decorated with graphene quantum dots was prepared using a novel approach•The material was successfully used for the extraction of PAHs and musks•A method for the determination of PAHs and musks in soil and effluents was developed In this study, the functionalization of melamine sponge (MeS) with graphene quantum dots (GQDs) and its use as a sorbent for the extraction of polycyclic aromatic hydrocarbons (PAHs) and musks from environmental samples are presented. The MeS@GQDs is prepared by modification of the MeS with GQDs in a one-pot, single-step, in situ synthesis, using citric acid as carbon source. The produced MeS@GQDs was used to develop and optimize an analytical method based on solid-phase extraction mode, for the subsequent analysis of soil samples and treated effluents exploiting the extraction properties of the synthesized MeS@GQDs. The developed method not only presented satisfactory repeatability (RSD
