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: The developed HPLC method demonstrated excellent performance, with low limits of detection and quantification of the tested catechins of 0.004-0.05 μg ml(-1) and 0.17 μg ml (-1), respectively, and recovery percentages of 96-101%.

TL;DR: In this article, a micelle mediated preconcentration method was developed for analysis of sunset yellow (SY) prior to its spectrophotometric determination, based upon cloud point extraction of the ion associate of SY and trioctylamine (TOA).

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: The ligation behavior of bis-benzoin ethylenediamine (B2ED) and benzoin thiosemicarbazone (BTS) Schiff bases towards Ru, Rh, Pd, Ni, Ni and Cu bases were determined and the characteristics of electron transfer process and stability of the complexes towards oxidation and/or reduction were assigned.
