In the title compound, [HgBr(2)(C(22)H(28)N(2)O(6))], the Hg(II) ion is bonded to two Br(-) ions and two N atoms of the chelating Schiff base ligand in a distorted tetra-hedral geometry. The Schiff base ligand adopts an E,E conformation. The dihedral angle between the planes of the two halves of the central N,N'-dimethyl-ethylenediamine part of the ligand is 2.3 (11)°. The crystal studied was t...

In the title compound, [Zn(CH(3)COO)(2)(C(6)H(16)N(2))], the Zn(II) atom is coordinated by two N atoms of one bidentate diethyl-ethylenediamine ligand and two O atoms of two acetate anions in a distorted tetra-hedral geometry. The acetate ligands are asymmetrically coordinated to the Zn atom with two different C-O distances of 1.234 (4) and 1.275 (4) Å. The dihedral angle between the N/Zn/N and...

The influence of selenium supplementation during chelation therapy to reduce body burden and toxicity of lead was investigated in rats. Selenium had marginal effects on liver, kidney and blood lead decorporation by calcium disodium ethylenediamine tetra acetic acid (CaNa2EDTA) and activation of inhibited delta- aminolevulinic acid dehydratase (ALAD) activity by calcium trisodium diethylenetriam...

The synthesis of ZnFe2O4 nanoparticles was performed using the solution combustion method with three types fuel, namely urea, glycine, and ethylenediamine tetra-acetic acid (EDTA) precursors (Zn(NO3)2.6H2O Fe(NO3)3.9H2O. process conducted in an open space at 300 °C for ± 1 h, resulting a brownish-black ZnFe2O4. Meanwhile, fuel type used affects physicochemical properties XRD analysis showed tha...

Conservation and restoration on archaeological objects in glass often involve the removal of materials from previous restorations comprise a deep knowledge about present past methodologies. This article presents literature survey critical analysis main used different stages intervention: cleaning, consolidation, joining fragments filling gaps. A considerable number products was identified, whic...

The usual methods for the determination of calcium in serum are lengthy procedures. Calcium may be precipitated as oxalate and the oxalate radical estimated by titration with potassium permanganate (Clark and Collip, 1925). The calcium oxalate may be converted to calcium carbonate which is estimated by titration with acid (Trevan and Bainbridge, 1926). Calcium may also be precipitated as calciu...

The trior tetrasodium salt of ethylenediaminetetraacetic acid (EDTA or Na EDTA) is a strong chelating agent for heavy metals and the alkaline earth metals, calcium and magnesium. By this action the activity of enzymes which are known to be influenced by calcium or magnesium is altered by the addition of EDTA; e.g., muscle adenylate kinase, which is accelerated by magnesium, is completely inacti...

LTHOUGH SUITABLE CONCENTRATIONS of many anticoagulants have been determined for mammalian blood, isosmolar concentrations are not generally available among vertebrates. In some instances the correct concentrations may be computed from known equations (1) or from known freezing-point depressions (ATs) at specific concentrations (2). The data are still fragmentary. In the present study, ATs cover...
