SPECTROPHOTOMETRIC- STUDY OF THERMODYNAMICS OF SOME HEAVY METAL COMPLEXES OF 4-(2 - PYRIDYLAZO) RESORCINOL IN BINARY ACETONITRILEDIMETHYLFORMAMIDE MIXTURES
The complexation reactions between 4-(2-pyridy1azo)-resorcinol and Cd ,H g and Pb io ns have been investigated in acetonitrile-dimethyEomamide mixtures at various temperatures using a spectrophotometric technique. The stoichiometry and the formation constants of the complexes formed in solution were calculated by computer refinement of absorbance-mole ratio data using nonlinear least-square ...
متن کاملLiquid chromatography of palladium and non-ferrous metal chelates with 1-(2-pyridylazo)-2-naphthol.
1-(2-Pyridylazo)-2-naphthol has been used for extraction concentration of palladium, copper, cobalt and nickel from aqueous solutions and subsequent separation of the chelates obtained, by means of high-pressure liquid chromatography. A technique for determining microamounts of palladium in aqueous solutions in the presence of 100-fold ratio of copper and 80-fold ratio of cobalt has been develo...
متن کاملSynthesis of some Novel Metal Complexes of 4-Hydroxy Benzopyran-2-Ones as Antimicrobial Agent
Complexes of 3-[{3-(3'-bromo phenyl)}-prop-2-enoyl]-4-hydroxy-6-methyl-2H-chromen-2-one with Cu(II), Ni(II), Fe(II), Co(II) and Mn(II) have been synthesized and characterized using elemental analysis, IR spectra and conductivity measurements. These studies revealed that they are having octahedral geometry of the type [ML2 (H2O)2]. In-vitro antimicrobial activity of all synthesized compounds and...
متن کاملInteraction of Human Serum Albumin with Ethyl 2-[2-(dimethylamino)-4-(4-nitrophenyl)-1,3-thiazole-5-yl]-2-oxoacetate as a Synthesized Ligand
The interaction of human serum albumin with Ethyl 2-[2-(dimethylamino)-4-(4-nitrophenyl)- 1,3-thiazole-5-yl]-2-oxoacetate was investigated by using isothermal titration UV-visible spectrophotometry in tris-buffer, pH 7.4. According to these results, it was found that there are a set of 4 binding sites for this ligand on HSA with positive cooperativity in the binding process. This thiazole deriv...
