The demand for analyzing low molecular weight polar and ionic components in body fluids, pharmaceutical formulations, food, environmental samples, and drinking water is increasing. Ion chromatography (IC) offers significant advantages over RPLC and HILIC due to a complementary chromatographic selectivity, a different retention mechanism, and a high tolerance toward complex matrices. A continuously regenerated membrane desalter simplifies the combination of IC‐applications with MS‐ or MS/MS‐detection, improving the sensitivity and specificity. Analytical workflows are streamlined, providing higher sample throughput. Combining IC with ICP‐MS simplifies the speciation analysis of inorganic and organic polar components. The knowledge about the distribution of an element among chemical species in a sample is essential due to significantly different toxicological or environmental properties. This annual review evaluates the literature published from late 2019 until November 2020.

“…Therefore, to effectively monitor and control Cr 2 O 7 2– in environmental media, it is urgent to develop a fast and convenient Cr 2 O 7 2– detection method. Currently, photoluminescence, − atomic absorption spectroscopy (AAS), chromatography, , inductively coupled plasma–mass spectrometry (ICP–MS), and electrochemical analysis are the most commonly used techniques for detecting Cr 2 O 7 2– . Considering the advantages of the simple operation, high sensitivity, and good selectivity of fluorescence spectroscopy, fluorescent probes are expected to be developed to provide an alternative method for the sensitive detection of Cr 2 O 7 2– in aqueous environments.…”

Nanoflakes are materials with high dispersion, a large specific surface area, and a high number of active sites that can provide a good platform for various fluorescence sensors and are very popular among researchers. In this study, a nanoflake-like zinc metal−organic framework (Zn-MOF) was successfully synthesized from the organic ligand 1,2,4,5-tetra(1H-imidazol-1yl)benzene and zinc nitrate. The synthesized Zn-MOF nanoflakes are extremely soluble in water and exhibit high fluorescence stability. Since Cr 2 O 7 2− can significantly quench the fluorescence of Zn-MOF aqueous solution, a rapid detection method for Cr 2 O 7 2− content in water was constructed with a linear range and linear correlation of 0.3−20 μM and 0.992, respectively. The fluorescence quenching constant of the Zn-MOF is K SV = 2.003 × 10 4 M −1 , and the detection limit for Cr 2 O 7 2− is as low as 0.09 μM. Through the study of fluorescence lifetime and UV absorption, it is proven that the mechanism of Cr 2 O 7 2− quenching the fluorescence of the Zn-MOF is the inner filter effect. In addition, even after being applied five times, the Zn-MOF still maintained good detection performance for Cr 2 O 7 2− . The proposed method was successfully applied to the determination of real water samples, confirming that it can be used as an alternative method for the detection of Cr 2 O 7 2− in environmental samples.

“…The drinking water treatment technologies able to be certified to international standards for reduction of TCr, Cr(VI), and Cr(III) individually, include adsorption, reverse osmosis, and distillation [11]. Recently, the different techniques, include, ion chromatography(IC), inductively coupled plasma mass spectrometry (ICP-MS) [12], stripping voltammetry (SV) [13], co-precipitation [14], flame atomic absorption spectrometry (F-AAS) [15], , inductively coupled plasma optical emission spectrometry (ICP-OES) [16], ion chromatography inductively coupled plasma-mass spectrometry (IC-ICP-MS) [17] and electrothermal atomic absorption spectrometry (ETAAS) [18] were used for determination of chromium species in water samples. Due to difficulty matrixes and low detection for chromium in water samples, treatment process such as liquidliquid extraction (LLE) [19], dispersive liquidliquid microextraction (DLLME) [20], magnetic solid-phase extraction (SPE) [21], dithiocarbamatemodified magnetite nanoparticles (DC-MNPs) [22] and cloud point extraction (CPE) [23] are developed.…”

In this research, 2-mercapto-1-methylimidazole a novel Task-specific ionic liquid (C4H6N2S; HS-CH3-IM) was used with a new approach for speciation of Cr (III, VI) from water samples by ultra-assisted dispersive ionic liquid-liquid microextraction procedure (USA-D-ILLME). Due to the procedure, 100 mg of HS-CH3-IM and 0.2 mL of acetone were mixed and injected into 10 mL of water or standard Cr (III) and Cr (VI) solution in the conical tube. After stirring for 5 min, the Cr (VI) and Cr (III) were extracted with a positive and negative charge of the thiol group (HS2+, HS-) in pH 2 or 8 and pH 5, respectively. The Cr (III, VI) loaded on the HS-CH3-IM was back-extracted in a liquid solution. Finally, the concentration of the Cr (III, VI) ions in a remained solution were measured with ET-AAS . The total chromium was determined in water samples by summarizing the Cr (VI) and Cr (III) contents. All parameters such as the amount of HS-CH3-IM, the sample volume, pH, and the shaking/centrifuging time were optimized. Under the optimal conditions, good linear range (LR), LOD, and enrichment factor (EF) were obtained 0.05–1.7 μg L−1, 15 ng L−1, and 19.82 respectively (RSD% < 1.45).
