Facile synthesis of hierarchical porous carbon from crude biomass for high-performance solid-phase microextraction

A microfluidic ratiometric electrochemical aptasensor for highly sensitive and selective detection of 3,3′,4,4′-tetrachlorobiphenyl

“…They include supercritical fluid extraction (SFE), 3 ultrasonic extraction, 4 Soxhlet extraction, 5 liquid–liquid extraction (LLE), 6 solid-phase extraction (SPE), 7 pressurized liquid extraction, 8 magnetic solid-phase microextraction (MSPE), 9 liquid-phase microextraction (LPME), 9 and solid-phase microextraction (SPME). 10 PCB77 is commonly detected using instrumental techniques such as high-performance liquid chromatography-mass spectrometry (HPLC-MS) and gas chromatography-mass spectrometry (GC-MS). 11 Conventional methods demonstrate remarkable precision and provide outstanding clarity, but they require expensive apparatus, skilled experts, and laborious and time-consuming procedures for preparing samples.…”

Carboxylated mesoporous carbon hollow spheres for the efficient solid-phase microextraction of aromatic amines

“…12 These porous carbon materials have showed excellent properties in SPME. 13–15 The high specific surface area caused by porous structure will improve the extraction ability and enrichment effect of SPME fibers. At the same time, the pore design and unique morphology are theoretically and practically proven to have a significant synergistic effect on adsorption as they shorten the mass transfer distance between the target and porous carbon material and effectively utilize the pore surface.…”

Carbonized silk fibers for in‐tube solid‐phase microextraction to detect polycyclic aromatic hydrocarbons in water samples

“…In contrast with these carbon materials, biomass carbon materials have prominent advantages such as low‐price, developed void and pipeline structure, more heteroatoms, abundant functional groups, renewable, and sustainable . The research that SPME coating from crude biomass for organic pollutants demonstrated that biomass carbon materials have excellent adsorption performance . Carbonized silk fibers designed as biomass carbon materials for sensors presented outstanding results in recent study, indicating that hybridized graphitic structures endowed silk fibers favorable performance .…”
