Correlations of Analytical Properties of Mercury Complexes With 2-hydroxythiophenol and Pyridine

Year: 2025

Type: article

Abstract: Five novel reagents were suggested for mercury (II) photometric determination: 2hydroxythiophenol and its derivatives (HTDs), namely 2,5-dihydroxythiophenol, 2-hydroxy-5fluorothiophenol, 2-hydroxy-5-chlorothiophenol, 2-hydroxy-5 - bromothiophenol, 2- hydroxy – 5- iodothiophenol. The molar absorptivity coefficient was (2.4-3.3)×104 (λ=450-480 nm). The optimal conditions for the complexation reaction correspond to pH range of 4.1 - 7.2. It has been proven that a compound with different ligands is formed in the ratio of Hg (II):HTDs:Py=1:2:2.
