Template Synthesis of Un-Symmetrical Tetradentate Schiff Base Complexes of Ni(II), Co(II), Zn(II) and X-ray Structure of Ni(II) Complex
Metal complexes, ML (M=Ni, Cu, Co and Zn) of unsymmetrical tetradentate schiff base have been synthesized by the template reaction of the half-units N-(1-hydroxy-2-acetonaphthone)-1-amino-2-phenyleneimine)(HL1) with 2-Pyrroleca-rbaldehyde. The complexes have been characterized by elemental analysis, IR, 1H NMR and UV spectroscopy. The crystal structure of the Ni(II) complex has been determine...
متن کاملEfficiency of Chitosan for the Removal of Pb (II), Fe (II) and Cu (II) Ions from Aqueous Solutions
Background: Heavy metals have been recognized as harmful environmental pollutant known to produce highly toxic effects on different organs and systems of both humans and animals. The aim of this paper is to evaluate the adsorption potential of chitosan for the removal of Pb(II), Fe(II) and Cu(II) ions from aqueous solutions. Methods: This study was conducted in laboratory scale. In this paper ...
متن کاملAnticonvulsant and Antimicrobial Activity of Cu (II), Zn (II) and Co (II) Complex of Isatin 3-Glycine
The role of Cu, Zn and Co in human physiology is well documented. Isatin and glycine have inhibitory effects on central nervous system. To capitalize on these features metal complexes of isatin-3-glycine were prepared and evaluated for anticonvulsant activity. The Cu (II) complex was found to be most active among the compounds. The compounds were screened against Staphylococcus aureus...
متن کاملTEMPLATE SYNTHESIS, CHARACTERIZATION OF HIGHLY UNSYMMETRICAL TETRADENTATE SCHIFF BASE COMPLEXES OF NICKEL (II) AND COPPER (II)
Nickel (II) and copper (II) complexes of highly unsymmetrical tetradentate Schiff base have been synthesized by the template reaction of half-units N-(1-hydroxy-2-acetonaphtone)-1-amino-2-phenyleneimine (HL) and N-(2-hydroxyacetophenone)-1-amino-2-phenyleneimine (HL1) with the glyoxalphenylhydrazone. The complexes have been characterized by elemental analyses, conductance, IR, 1H NMR and UV spe...
متن کاملBiosorption of Lead (II) and Zinc (II) ions by pre-treated biomass of phanerochaete chrysosporium
The biosorption of heavy metals can be an effective process for the removal of such metal ions from aqueous solutions. In this study, the adsorption properties of nonliving biomass of phanerochaete chrysosporium for Pb (II) and Zn (II) were investigated by the use of batch adsorption techniques. The effects of initial metal ion concentration, initial pH, biosorbent concentration, stirring speed...
