“…Preparation of graphene oxide/Fe3O4 magnetic nanoparticle sorbent: In this study, Fe3O4 were combined with GO to support and strengthen the material to produce a stable magnetic sorbent. Graphene and graphene oxide (GO) has become the most favoured and effective sorbent in analytical chemistry since it has very large surface area, which is 2630 m 2 g -1 [18,19]. Graphene is hydrophobic which determine its function in water system.…”

A simple and rapid magnetic solid-phase extraction based on reduced graphene oxide/ferroferic oxide (rGO/Fe3O4) coupled with high performance liquid chromatography-diode array detector (HPLC-DAD), was proposed for the determination of naproxen and diclofenac sodium of non-steroidal anti-inflammatory drugs (NSAIDs) and bisphenol-A residue in tap water sample. Fe3O4 was assembled with graphene oxide by facile method. Several important parameters, such as extraction time, desorption time and desorption solvent were studied and optimized. Optimal conditions were then used for the extraction of NSAIDs and bisphenol-A from real samples, prior to HPLC-DAD analysis using C18 column. The proposed method provides good linearity in the range of 1.0-5.0 mg L-1 (R2 naproxene = 0.9983, R2 diclofenac = 0.9960) for NSAIDs and R2 = 0.9919 for bisphenol-A; limit of detection of 0.031 mg L-1 and 0.023 mg L-1 for naproxen and diclofenac, respectively and 0.1785 mg L-1 for bisphenol-A; limit of quantification for naproxen and diclofenac were 0.102 and 0.076 mg L-1, respectively and 0.5949 mg L-1 for bisphenol-A; relative recoveries between 66.21 and 105.60 % for diclofenac and naproxen, respectively and 72.74 % for bisphenol-A; and acceptable reproducibility relative standard deviation (RSD, n = 3) of 6.79 and 11.32 % for diclofenac and naproxen, respectively and 0.93 % for bisphenol-A. The method was successfully applied to tap water sample and the results indicates that small residue of bisphenol-A is present the sample while no traces of NSAIDs was detected.

Safety analysis of aquatic products has been a challenge in recent years due to the serious matrix interference, complex characteristics, and ultra-low content of analytes. Introducing advanced materials to sample preparation technique can greatly improve the extraction, enrichment, and separation for further qualification and quantification of target analytes by coupling with consequent analytical technologies. Based on this scope, this review is mainly introducing advanced materials on the sample preparation for safety analysis of aquatic products in the past decade. After introducing the importance of the corresponding advanced materials, advanced materials are used for the sample preparation and in the improvement of safety analysis result of aquatic products. Advanced materials for sample preparation of aquatic products were reviewed including carbon materials, metal organic frameworks, covalent organic frameworks, molecularly/ions imprinted polymers, etc. Then, applications of the advanced materials for the analysis of specific fishery analytes (antibiotics, anesthetic, preservatives, etc.) were briefly introduced. Conclusions and perspectives on advanced materials for sample preparation and safety analysis of aquatic products were also presented.

Novel Approaches Utilizing Metal-Organic Framework Composites for the Extraction of Organic Compounds and Metal Traces from Fish and Seafood

The determination of organic and inorganic pollutants in fish samples is a complex and demanding process, due to their high protein and fat content. Various novel sorbents including graphene, graphene oxide, molecular imprinted polymers, carbon nanotubes and metal-organic frameworks (MOFs) have been reported for the extraction and preconcentration of a wide range of contaminants from fish tissue. MOFs are crystalline porous materials that are composed of metal ions or clusters coordinated with organic linkers. Those materials exhibit extraordinary properties including high surface area, tunable pore size as well as good thermal and chemical stability. Therefore, metal-organic frameworks have been recently used in many fields of analytical chemistry including sample pretreatment, fabrication of stationary phases and chiral separations. Various MOFs, and especially their composites or hybrids, have been successfully utilized for the sample preparation of fish samples for the determination of organic (i.e., antibiotics, antimicrobial compounds, polycyclic aromatic hydrocarbons, etc.) and inorganic pollutants (i.e., mercury, palladium, cadmium, lead, etc.) as such or after functionalization with organic compounds.
