The structure of the title compound, [Mg(2)(C(4)H(9))(C(14)H(18)NO)(3)], contains two Mg atoms bridged by two μ(2)-O atoms from two of the three ketiminate ligands, while the third ketiminate is strictly chelating to one of the Mg atoms, which is thereby five-coordinate. In place of a chelating ligand, the second Mg atom is ligated by a single terminal n-butyl group and thus is four-coordinate....

This mini-review covers chelating sorbents anchored to silica gel and their analytical applications for the preconcentration, separation and determination of trace metal ions, focussing mainly on the last 20 years. The article summarizes also the experience gathered by our research group in the synthesis and characterization of new modified silica gels "via silanization", and their affinity tow...

pot experiment was carried out to investigate the effects of ethylenediaminetetraacetic acid (edta) on some morphological characteristics of thlaspi caerulescens l., and also on the accumulation of lead (pb) and zinc (zn) in roots and shoots of t. caerulescens l.. experiments were then set up in three treated pots with doses of 3, 6 and 9 mmol kg-1 of edta and control pots (c: uncontaminated so...

BACKGROUND Antioxidant and chelating activities were determined in protein hydrolysates that were produced by treating a protein isolate of a non-toxic genotype of Jatropha curcas with the protease preparation alcalase. RESULTS 50 min protein hydrolysate with a degree of hydrolysis of 31.7% showed highest antioxidant and chelating activity. These activities were also determined in six peptidi...

In this work, we evaluated antioxidant and metal chelating activities of common bean proteins. Protein fractions were produced by using extraction with organic (method 1) or aqueous (method 2) solvents. Results evidenced that the amount of proteins extracted through method 2 was higher than method 1, probably due the chemical difference between solvents. The antioxidant activity of hard-to-cook...

The studies on removal of Vanadium were conducted using Granulated Activated Carbon (GAC) in combination with Chelating agents. Ethylene di-amine Tetra Acetic Acid (EDTA) and Nitrilo Tri Acetic Acid (NTA) at 25oC. The adsorption Efficiency was studied in the pH range of 2-8. The results reveals that Langmuir and Freundlich isotherms are followed during adsorption process with the chelating agen...

Chelation is a bonding formed between a metal ion and legend. Chelating improves the absorption of the mineral from the digestive tract. The level of chelated minerals in livestock feeding is typically added at 25-30% of the total mineral in a feed. Chelated minerals have improvement in reproduction, health, soundness and growth. Natural feed with strong chelating properties includes dry melt r...

The cornerstone of the treatment of Wilson’s disease is a reduction of copper levels in vivo using the orallyadministered chelating agents D-penicillamine and trientine dihydrochloride. Patients with side-effects from receiving multiple blood transfusions for the amelioration of inherited anaemias are also successfully treated with chelating agents. Blood transfusion elevates these patients’ ir...
