Spectrophotometric Study of Cobalt, Nickel, Copper, Zinc and Lead Complexes with Methylthymol Blue in Binary Water-Methanol Mixtures
The complexation reactions between methylthymol blue (MTB) and Co2+, Ni2+, Cu2+, Zn2+ and Pb2+ ions have been studied in different water-methanol mixtures at pH 4.45 and 25 °C by a spectrophotometric technique. The stepwise stability constants of the resulting 1:1 and 2:1 (metal ion to ligand) complexes were determined from the absorban...

متن کاملSeparation of cobalt and nickel by solvent extraction with two mutually immiscible ionic liquids.
The proof-of-principle for the separation of metals by solvent extraction using two mutually immiscible ionic liquids is given. Cobalt was extracted from the ionic liquid 1-ethyl-3-methylimidazolium chloride to the ionic liquid trihexyl(tetradecyl)phosphonium bis(2,4,4-trimethylpentyl)phosphinate. A distribution ratio of 44 was obtained. Cobalt could be selectively separated from nickel, with a...
متن کاملSynthesis, Characterization and Antimicrobial Studies on Bivalent Copper, Nickel and Cobalt Complexes of Thiosemicarbazone
A series of metal complexes of Cu(II), Ni(II) and Co(II) having the general composition [M(L)2]Cl2 [where L= m-nitrobenzaldehyde-4-(4'-sulphoamidephenyl)-3-thiosemicarbazone; M = Cu(II), Ni(II) and Co(II)] have been prepared and characterized by elemental analysis, spectral (IR and H NMR) studies, molar conductance, magnetic susceptibility measurements and thermogravimetric analysis. The spectr...
متن کاملComparative gas sensing in cobalt, nickel, copper, zinc, and metal-free phthalocyanine chemiresistors.
The sensitivities of metallophthalocyanine (MPcs: M = Co, Ni, Cu, Zn, and H(2)) chemiresistors to vapor phase electron donors were examined using 50 nm MPc films deposited on interdigitated electrodes. Sensor responses were measured as changes in current at constant voltage. Analytes were chosen to span a broad range of Lewis base and hydrogen bond base strengths. The MPc sensor responses were ...
