TL;DR: In this article, the authors summarized the published innovations in nanomaterial-based optical sensors for the detection of Hg 2+ according to different sensing strategies, including colorimetric, fluorescent and surface enhanced Raman scattering detection.

TL;DR: In this paper, a novel and generally applicable IIPs strategy was proposed for simultaneous preconcentration and removal of four heavy metal ions based on dithizone chelation, which can effectively identify water-soluble ions especially heavy metal ion, however, multi-ion imprinting is rarely performed owing to possible crossreactivity and matrix interferences.

TL;DR: This method was demonstrated to be simple, convenient, rapid, cost‐effective, and environmentally benign, and could be used as an ideal alternative to existing methods for analyzing trace residues of mercury species in water samples.

TL;DR: An efficient method based on dispersive liquid-liquid microextraction coupled with micellar electrokinetic chromatography has been developed for determination of three phenoxyacid herbicides (PAs) of 2,4dichlorophenoxybutyric acid (2,4-DB), dicamba and 2.4-D), in environmental water samples as discussed by the authors.

TL;DR: Under the optimized extraction conditions, UA-DLLME exhibited strong enrichment ability for the four PAEs, and is a convenient, speedy, environmentally benign method for the routine analysis of PAEs in water samples.
