Mercuric Hg(II) species form complexes with natural dissolved organic matter (DOM) such as humic acid (HA), and this binding is known to affect the chemical and biological transformation and cycling of mercury in aquatic environments. Dissolved elemental mercury, Hg(0), is also widely observed in sediments and water. However, reactions between Hg(0) and DOM have rarely been studied in anoxic en...

Mercury exposure is the second-most common cause of toxic metal poisoning. Public health concern over mercury exposure, due to contamination of fish with methylmercury and the elemental mercury content of dental amalgams, has long been a topic of political and medical debate. Although the toxicology of mercury is complex, there is evidence for antioxidant protection in the prevention of neurolo...

Monolayers based on the novel multifunctional compound K29 (the amphiphilic and photosensitive derivative of dithiacrown-ethers) were obtained and investigated. The studied ion-selective and photosensitive properties of K29 in monolayers demonstrated its ability to form complexes with mercury cations which were detected by significant changes in the K29 monolayer isotherms and absorption spectr...

The synthesis of novel mercury (II) complex with new ligands derived from Carbohydrazides has been reported. The complexes have general composition [ HgL2X2], Where L= Carbohydrazone and X = Cl-, NO3 . The ligand carbohydrazone behave as neutral bidentate Ligand through the carbonyl oxygen and azomethiene nitrogen. On the basis of elemental analysis, Electrochemical and spectroscopic studies, t...

Lead forms the complexes with xylenol orange in the basic solution. An adsorptivedifferential pulse stripping method for the determination of lead is proposed. The procedureinvolves an adsorptive accumulation of lead on a hanging mercury drop electrode (HMDE) inthe presence of xylenol orange, followed by reduction of adsorbed lead by voltammetric scanusing differential pulse modulation. The opt...

Zn(II), Cd(II) and Hg(II) complexes of N-methyl-N-phenyl dithiocarbamate have been synthesized and characterized by elemental analysis and spectral studies (IR, (1)H and (13)C-NMR). The single crystal X-ray structure of the mercury complex revealed that the complex contains a Hg centre with a distorted tetrahedral coordination sphere in which the dinuclear Hg complex resides on a crystallograph...

The synthesis and characterization of cadmium and mercury complexes of selenocyanate of the type [(L)M(SeCN)2] are described, where L is L-Histidine (His) or L-Glycine (Gly) and M is Cd(2+) or Hg(2+). These complexes are obtained by the reaction of 1 equivalent of respective amino acids with metal diselenocyanate precursor in a mixture of solvents (methanol : water = 1 : 1). These synthesized c...

Differential pulse anodic stripping voltammetric study of zinc-ethylenediamine complex has been investigated using thin mercury film coated glassy carbon electrode at 30°C. The overall work was carried out at constant ionic strength (I = 0.20 mol dm -3 ) and pH (9.10±0.10). The electrode processes were found to be reversible and diffusion controlled. The results revealed that zinc forms three (...
