Eco‐Friendly and Green Biochar Sorbent–Extraction Techniques for Pharmaceuticals, Environmental, and Food Analysis—A Review

Journal of Separation Science, Год журнала: 2025, Номер 48(1)

Опубликована: Янв. 1, 2025

The most important aspect of sorbent-based approaches is the use a sustainable, readily available, and cost-effective sorbent material for sample analysis. Biochar an emerging prominent various applications in techniques due to its availability, affordability, eco-friendly nature, porosity, pore structure, abundance aliphatic aromatic carbon structures, abundant oxygen-containing functional groups. On basis numerous benefits biochar, this review discusses why biochar preferred sorptive-based techniques. In addition, provides brief evaluation biochar-based sorptive approaches, including solid-phase extraction (SPE)/microextraction (SPME), magnetic SPE/SPME, in-tube SPME, pipette-tip micro SPE, thin-film microextraction. Furthermore, each section briefly overviews studies analyses applications, pharmaceuticals, environmental, food. Most importantly, on literature review, that require further investigation applications.

Monitoring Poly(methyl methacrylate) and Polyvinyl Dichloride Micro/Nanoplastics in Water by Direct Solid-Phase Microextraction Coupled to Gas Chromatography–Mass Spectrometry

Analytical Chemistry, Год журнала: 2024, Номер 96(26), С. 10772 - 10779

A simple, sustainable, and sensitive monitoring approach of micro/nanoplastics (MNPs) in aqueous samples is crucial since it helps assessing the extent contamination understanding potential risks associated with their presence without causing additional stress to environment. In this study, a novel strategy for qualitative quantitative determination MNPs water by direct solid-phase microextraction (SPME) coupled gas chromatography–mass spectrometry (GC-MS) was proposed first time. Spherical poly(methyl methacrylate) (PMMA) irregularly shaped polyvinyl dichloride (PVDC) were used evaluate feasibility performance method. The results demonstrated that both PMMA PVDC efficiently extracted homemade SPME coating nitrogen-doped porous carbons (N-SPCs) exhibited sufficient thermal decomposition GC-MS injection port. Excellent extraction performances N-SPCs are attributed hydrophobic cross-linking, electrostatic forcing, hydrogen bonding, pore trapping. Methyl methacrylate identified as marker PMMA, while 1,3-dichlorobenzene 1,3,5-trichlorobenzene indicators PVDC. Under optimal conditions, method ultrahigh sensitivity, limit detection 0.0041 μg/L 0.0054 Notably, programmed temperature injector developed discriminate eliminate interferences intrinsic indicator compounds. Owing integration sampling, extraction, injection, into one step SPME, demonstrates exceptional eliminating necessity complex sample pretreatment procedures use organic solvents. Finally, successfully applied real samples.
