Development of a high-efficiency and environmentally friendly melamine–formaldehyde resin-based solid phase microextraction fiber for enhanced extraction of polycyclic aromatic hydrocarbons from environmental water

Abstract

An innovative solid-phase microextraction (SPME) fiber coating, melamine-formaldehyde resin (MFR), was synthesized with a green cross-linker, paraformaldehyde, and exhibited high heat resistance (up to 350 °C). Seven polycyclic aromatic hydrocarbons...

Green synthesis of water-compatible molecularly imprinted resin on graphene oxide for highly selective extraction of chlorogenic acid in aqueous systems

“…In line with the principles of green analytical chemistry, low-consumption and miniaturized sample pretreatment technologies with reduced organic solvent usage, such as dispersive liquid–liquid microextraction, solid-phase microextraction, and miniaturized pipette-tip solid-phase extraction, are favored. 9,10…”
