TL;DR: An ionic liquid-based ultrasonic-assisted extraction (ILUAE) method has been developed for the effective extraction of piperine from white pepper powder and indicates that both the characteristics of anions and cations have remarkable effects on the extraction efficiency.

TL;DR: In this paper, an in situ polymerization procedure using glycidyl methacrylate (GMA) as a monomer and trimethylolpropane trimethacrylated (TRIM) and ethylene dimethacarylate (EDMA) cross-linkers, respectively, was applied to characterize the morphology of the end of a monolithic capillary and mercury intrusion porosimetry to characterize a polymer rod prepared within the confines of a stainless steel column.

TL;DR: The proposed method was demonstrated to be feasible, simple, solvent-saving and easy to operate for the trace analysis of NBs in environmental water samples.

TL;DR: In this paper, a new application of pyrolytic methylation was developed to determine benzoic acid in soft drinks by gas chromatography (GC) without using any pretreatment procedures and special pyprolyzer.

TL;DR: An ultrasound-assisted magnetic SPE procedure with an Fe3 O4 -grafted graphene nanocomposite as the magnetic adsorbent has been developed to determine seven polychlorinated biphenyls simultaneously in 200 mL environmental water samples, in combination with GC-MS/MS.
