Studies on thermodynamic and formation constants of metal complexes in solution

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

CRITICAL EVALUATION OF EQUILiBRIUM CONSTANTS IN SOLUTION STABILITY CONSTANTS OF METAL COMPLEXES

Metal (II) Complexes of Fluconazole: Thermal, XRD and Cytotoxicity Studies

We report thermal, X-ray diffraction (XRD) and cytotoxicity studies of complexes of fluconazole (FCZ) with Cu (II), Fe(II), Cd(II), Co(II), Ni(II), and Mn(II). From XRD measurements, FCZ and its metal complexes were identified as polycrystalline. Marked differences in the X-ray patterns of drug and its metal complexes revealed that the complexes are indeed different compounds and not just the m...

Metal–5-Fluorouracil–Histamine Complexes: Solution, Structural, and Antitumour Studies

Solution studies were performed pH-metrically to study the interaction of Co(II), Ni(II), Cu(II), Zn(II) and Cd(II) metal ions with 5-fluorouracil (5FU) and histamine (Hm) separately (binary) and in the presence of each other (ternary) at 25+/-0.1( degrees )C temperature and a constant ionic strength of 0.1 M NaNO(3) in aqueous solution. The ternary complexes have been found to be more stable t...
