Selective extraction of iron(III) from aqueous nitrate solution in the presence of cobalt(II), copper(II) and nickel(II) ions using bis(delta2-2-imidazolinyl)-5,5'-dioxime.
The feasibility of using bis(delta2-2-imidazolinyl)-5,5'-dioxime (H2L) for the selective extraction of iron(III) from aqueous solutions was investigated by employing an solvent-extraction technique. The extraction of iron(III) from an aqueous nitrate solution in the presence of metal ions, such as cobalt(II), copper(II) and nickel(II), was carried out using H2L in binary and multicomponent mixt...
متن کاملSynthesis, Characterization and Biological Studies of 2-(4-Nitrophenylaminocarbonyl)Benzoic Acid and Its Complexes with Cr(III), Co(II), Ni(II), Cu(II) and Zn(II)
Cr(III), Co(II), Ni(II), Cu(II) and Zn(II) salts of 2-(4-nitrophenylaminocarbonyl)benzoic acid were characterized by physical, analytical and spectroscopic studies and checked for their in-vitro antimicrobial activity against three bacterial strains, Mycobacterium smegmatis (Gram +ve), Escherichia coli (Gram -ve), Pseudomonas aeuroginosa (Gram -ve) and three fung...
متن کاملBiological activity study on Indole acetic acid and its cobalt ( II ) , nickel ( II ) and copper ( II ) complexes
Indole acetic acid complexes have been prepared and characterized by elemental analysis, H NMR and UVVisible spectra and electrochemical measurements. The antimicrobial properties of these compounds have been evaluated against the test strains (A.niger, St. aureusStreptococcus aureus) and thus a significant use of such compounds as antibacterial agent is reported. The biological activity data s...
متن کاملSynthesis, characterization and biological activity of manganese(II), iron(II), cobalt(II), nickel(II) and copper(II) schiff base complexes against multidrug resistant bacterial and fungal pathogens
A Schiff base was prepared from the interaction of ethanolic solutions of 2-hydroxy-1– naphthaldehyde and butylenediamine. The complexes were synthesized by refluxing the mixture of ethanolic solutions of the Schiff base and respective metal (II) chloride. Their solubility, melting point/decomposition temperature, molar conductance, elemental analysis and IR were carried out. The melting point ...
متن کاملRemoval of Nickel (II) ions from aqueous solutions using Iron (III) oxide nanoparticles: study of kinetic, isotherm and thermodynamic models
Background and Objective: Due to the existence of industries such as stainless steel, the presence of nickel (II) ions in water and wastewater has been reported at high concentrations. Removal of nickel (II) ions from wastewater and the environment are of primary importance. In this study, iron (III) oxide nanoparticles were studied as an adsorbent for removal of Ni (II) ions from water in the ...
