Spectrofluorimetric determination of magnesium ions in water, ampoule, and suspension samples using a fluorescent azothiazol‐benzenesulfonamide derivative

Abstract

In this study, a fluorescence azothiazol-benzenesulfonamide derivative (M-sensor) was prepared for the determination of Mg 2+ ions in different samples. The utilized M-sensor exhibited an emission fluorescence activity at 587 nm upon excitation at 537 nm. The developed method was based on the quenching effect of Mg 2+ ions on

Density functional theory study of crown ether–magnesium complexes: from a solvated ion to an ion trap

“…Sensors for metal cation detection possess ionophores sensitive and selective towards target ions, and measurement of the optical or electrochemical response of ion-ionophore complex is at the heart of modern analytic techniques. [3][4][5][6][7][8][9][10][11][12][13][14][15][16] Mg 2+ and other metal cation traps attract the cation by their electronegative atoms within, for example, coumarin derivatives, [4][5][6][7] Schiff bases, [8][9][10] or cyclic ethers. [11][12][13] The latter, known as crown ethers, 17 proved successful in cation capture [18][19][20][21][22][23][24][25][26] due to the negative charge concentrated in the center of the ring.…”

Detection and Selective Removal Strategy of Thorium Ions Using a Novel Fluorescent Ligand and Hybrid Mesoporous γ-Al2O3-like Nanoneedles

“…Accordingly, numerous scientists have started focusing on the field of Th­(IV) detection through fluorescence techniques. , Despite the fact that several fluorescent sensors for radioactive metals have been produced, only a small number of sensors have been fabricated to detect Th­(IV) ions in aqueous solutions. Therefore, we strive to highlight the field of extraction, detection, and removal of Th­(IV) ions from aqueous solutions through developing sensitive and selective fluorescent-ligands@adsorbent. , Due to the fluorescent-ligands@adsorbents containing multiple and various electron-donating groups, these groups have the potential to form coordination bonds and many chelating rings with the target ions.…”
