Synthesis of a novel bistriazene reagent 4,4′-bis[3-(4-phenylthiazol-2-yl)triazenyl]biphenyl and its highly sensitive color reaction with mercury(II)

Synthesis and Characterization of HgSe Nanostructure Using a Novel Precursor

“…The variety of possible Schiff base metal complexes with wide choice of ligands, and coordination environments, has prompted us to undertake research in this area [5]. Mercury containing ligands e.g., mercuric and mercurous are known to form stable complexes with class b metal ions, such as gold(I) [6,7] and se(II) because mercury is considered to be a soft Lewis base [8]. Recently, there has been an increased interest in the synthesis and characterizations of HgSe because it has a unique combination of properties; which makes it a candidate material for detailed investigations of solid state phenomena [9].…”

A Novel Azobenzene-Based Fluorescent Sensor for Selective Detection of Mercury Ion

“…Our increased understanding of the deleterious effects of mercury exposure has sparked the interest in the development of new tools for detecting Hg 2+ in the environment [2,3]. Because of great sensitivity, fluorescent chemosensor combining ionophores and fluorophores are commonly considered superior [4,5].…”

Part 1. Spectrophotometric determination of trace mercury (II) in dental-unit wastewater and fertilizer samples using the novel reagent 6-hydroxy-3-(2-oxoindolin-3-ylideneamino)-2-thioxo-2H-1,3-thiazin-4(3H)-one and the dual-wavelength β-correction spectrophotometry

“…A series of chromogenic reagents has been reported for mercury (II) determination in different samples [24][25][26][27][28]. Most of these methods are suffered from the lack of sensitivity due to the significant interference of the excess of chromogenic reagent with the analyte at max .…”
