in this thesis, we exploit a simple and suitable method for immobilization of copper(ii) complex of 4?-phenyl-terpyridine on activated multi-walled carbon nanotubes [amwcnts-o-cu(ii)-phtpy]. this nanostructure was characterized by various physico-chemical techniques. to ensure the efficiency and fidelity of copper species, the implementation of three-component strategies in click-chemistry all...
A new high energetic copper(II) complex, [Cu(μ-DAMT)Cl2]2, was prepared in reaction between 4,5-diamino-3-methyl-4H-1,2,4-triazol-1-ium chloride (DAMT.HCl)and copper(II) nitrate and identified by elemental analysis and spectral characterization. The spectral and physical characterizations of the product confirm formation of a binuclear structure of the copper(II). In the predicted structure of ...
background: a great deal of evidence has indicated that oxidatively modified ldl plays a critical role in the initiation and progression of atherosclerosis. antioxidants that can prevent ldl oxidation may act as antiatherogens. copper is a candidate for oxidizing ldl in atherosclerotic lesions. the binding of copper ions to ldl is usually thought to be a prerequisite for ldl oxidation by copper...
A simple and rapid method has been developed for solvent extraction and spectrophotometric determination of copper (II) using o-methylphenyl thiourea (OMPT) as a sensitive reagent. The basis of proposed method is formation of copper (II)-OMPT complex. Copper (II) was extracted with 0.020 mol L-1 OMPT in chloroform from aqueous solution in 0.075 mol L-1 potassium iodate. The absorbance of comple...
Background: The oxidative modification of low density lipoprotein (LDL) may play an important role in atherogenesis. Mechanism of LDL oxidation and factors that determine its susceptibility to oxidation is unknown. Copper is account as an attributing factor in LDL oxidation atherosclerotic lesions. The binding of copper ions to LDL is usually thought to be a prerequisite for LDL oxidation by co...
the copper(ii) complex [cu(pic)2]·2h2o was synthesized with 2-picolinic acid (hpic) and copper acetate as reactants by room temperature solid-solid reaction. the composition and structure of the complex was characterized by elemental analyses, single crystal x-ray diffraction, x-ray powder diffraction, ft-ir spectroscopy and thermogravimetry-differential scanning calorimetry. the crystal struct...
copper extraction from heap 3 low grade ore at sarchechmeh is limited due to its mixed composition (copper oxide and sulphide minerals). changing this heap to a bioheap could improve the copper recovery.

5-((4-alkoxyphenyl)azo)salicyladehyde, 5-((4-alkoxyphenyl)azo)-n-(npentyl, ndodecyl)-salicyladimine and bis [5-((4-alkoxyphenyl)azo)-n-(npentyl, ndodecyl)-salicyladiminato]copper(ii) [alkoxy=oncnh2n+1; n=3-7] homologues were synthesized and characterized by elemental analyses, mass and ir spectra. all complex homologues are thermally stable. cyclic voltammetric studies indicated that all copper...
sarcheshmeh copper complex is the largest producer of copper in iran. with copper production, high amounts of so2 are being produced in this complex and emmited into the environment. so, in this study, the social optimum level of so2 released from this complex and the optimal tax rate will be evaluated. for this purpose, md and mac curves were estimated. the wtp for the reduction of so2 emissio...
