TL;DR: A comprehensive review of liquid liquid microextraction (DLLME) techniques for analysis of trace emerging pesticides in water is presented in this paper, where thin-layer stripping voltammetric techniques at surface modified electrodes and spectrofluorimetric techniques coupled and implemented with DLLME are discussed.

TL;DR: In this article, a simple procedure for dispersive liquid-liquid microextraction (DLLME) of Cr(III) and Cr(VI) species has been established, where the ion associate represented by halochromate (CrO 3 Cl − ) anion and rhodamine 6G hydrochloride dye (RG + ) cation is selectively extracted via DLLME following micro-volume UV-Vis spectrometric detection.

TL;DR: Recent trends in pre-concentration toward miniaturization, automation, and possible coupling with electrochemical techniques, surface-enhanced Raman scattering, spectrofluorimetry, and lateral flow protocols to be exploited for the development of rapid, facile, and sensitive on-site determination strategies for BAs are discussed.

TL;DR: In this paper, a fast and selective method for cadmium(II) removal from water by procaine hydrochloride (PQ+·Cl−) immobilized polyurethane foam (PUFs) sorbent was developed.

TL;DR: A micro-volume spectrofluorimetric coupled ultrasound-assisted ion association dispersive liquid-liquid microextraction (USA-IA-DLLME) procedure for the total determination and speciation of chromium(III & VI) species has been established as mentioned in this paper.
