“… 36 , 138 , 139 , 141 For example, proteins that contain covalently bound metals ( e.g. , Se 142 and As 143 ) are amenable to conventional strategies, including multidimensional methods involving reverse-phase, hydrophilic liquid chromatography (HILIC), and size exclusion chromatography (SEC) and ion exchange. In general, the principle of the LC-ICP-MS technique combines the potential for high-resolution separation of metallobiomolecules by LC with the elemental detection sensitivity of ICP-MS. 36 , 139 Although LC-ICP-MS presents diverse applications in metallomics, especially those associated to metalloproteins, the instability of the analyte signal caused by a low flow LC system, as well as the use of a mobile phase with high concentration of salt or with high composition of organic solvent, can negatively affect its stability and reduce the sensitivity of the technique, causing misunderstandings in quantification studies.…”

“…Different kinds of techniques have been employed for the detection of toxic metal ions. Until now, well-known methods for the identification of toxic metal ions have been based primarily on instrumental methods, including atomic absorption spectroscopy, − ICP-MS, − and electrochemical analysis. − However, these approaches suffer from some problems such as being time-consuming, having a high cost, and are difficult to transfer. So, it is necessary to develop a novel and effective method for detecting Cr(VI) and Mn(VII) contaminants.…”

A new fluorescent supramolecular organic framework (HNU-35) has been constructed, which is a threedimensional structure composed of hydrogen bonding interactions between the carboxyl groups of adjacent 1,1,2,2-tetrakis(4carboxyphenyl)ethylene (H 4 TCPE). HNU-35 exhibits good acid−base stability and can be stable in the pH range of 1−11. Because of its good stability and luminescence emission in water, the anionic detections of HNU-35 are evaluated. All results show HNU-35 is a highly selective luminescent sensing material for the detection of Cr(VI) and Mn(VII) in aqueous solution, and the detection limits of Cr 2 O 7 2− , CrO 4 2− , and MnO 4 − are 26.46 nM, 20.91 nM, and 13.56 nM. HNU-35 also shows good detection effect in the water samples of the lake and sea, which indicate HNU-35 can serve as a potential sensor for Cr(VI) and Mn(VII) detection.

Carbon dots and metal-organic frameworks (MOFs) have been widely used in a variety of applications such as sensing, energy storage, and catalysis, with fewer applications in electrochemical sensing. In this study, C-Dots/UiO-66-NH2 was prepared as a modified material for glassy carbon electrodes for the detection of cadmium and lead ions in water by electrochemical methods (DPV) by selecting m-phenylenediamine as a source of carbon dots and amino-functionalized zirconium-based metal-organic frameworks, which are the combination of these two popular materials. Due to the complexation of amino groups with metal ions, a sufficient amount of amino groups provided a good interface for the adsorption of metal ions. Under the optimal deposition conditions, C-Dots/UiO-66-NH2 exhibited good linearity and excellent detection limits for metal ions (Cd2+, Pb2+) in the concentration range of 30 to 180 µg/L. The results showed that C-Dots/UiO-66-NH2 was suitable for the determination of Cd2+ and Pb2+ in water. In addition, the C-Dots/UiO-66-NH2/GCE sensor has good immunity to interference and detection stability.
