Mercury is a naturally occurring metal, which can exist in several forms. Metallic mercury is a shiny, silver-white, odorless liquid, which forms a colorless, odorless gas if heated. Mercury combines with other elements such as chlorine, sulfur, or oxygen to form inorganic mercury compounds or salts, which are usually white solids. Mercury also combines with carbon to make organic mercury compo...
In this research N(2-chloro-phenyl)4-nitro-thiobenzamide as a ligand was synthesized. One mmol of mercury oxide was added to the solution of 1 mmol ligand in 45 ml chloroform and after 90 min the mixture through celite or BaS to remove unreacted mercury(II) compounds. The yellow crystals, which formed by slow evaporization, was separated and recrystallized from chloroform as fine yellow crystal...
The present work describes the synthesis of a variety organotellurium compounds. first part new series compounds containing azomethine groups. Reaction (E)-(4-((1,7,7-trimethyl bicyclo[2.2.1]heptan-2-ylidene)amino)phenyl)mercury(II)chloride and (E)-(5-methyl-2-((1,7,7-trimethylbicyclo[2.2.1]heptan-2-ylidene)amino)phenyl) mercury(II)chloride with tellurium tetrabromide in 2:1 mole ratio yielded ...
Two organomercury haptens were synthesized via the classical oxymercuration reaction. An intramolecular oxymercuration reaction was the strategy employed to prepare a structurally simple, but chemically robust, organomercury hapten that was conjugated to chicken immunoglobulin G (IgG). The resulting immunogen afforded mouse anti-mercury antibodies that were evaluated in an enzyme-linked immunos...
First, Schiff base iminopyridine ligands has been prepared by the condensation between primaryamines, different substituted anilines and active carbonyl group of pyridine carboxaldehyde, thenthe complexes [diiodo (3-ethylphenyl) pyridine-2-yl methylene amine] mercury(II), complex a,[dibromo (2,5-dimethylphenyl) pyridine-2-yl methylene amine] mercury(II) complex b, and[dinitrato bis-(2,6-dimethy...
Background and objectives: Methyl mercury can carry out harmful effects on the reproductive, respiratory, and nervous system of human. Moreover, mercury is known as the most toxic heavy metal in nature. Fish and seafood consumption is the major MeHg exposure route for human. The present study tries to cover researches which have been conducted on mercury levels in 21 species of fish from Persia...
A sensitive fluorescence optosensing method for the determination of Hg(II) in water samples is described. The method, using a flow injection technique, is based on the immobilization on a non-ionic-exchanger solid support (packed in a flow cell placed in a conventional fluorimeter) of the thiochrome formed by the oxidation of thiamine with Hg(II) in a continuous flow carrier at pH 8.1. Experim...
