Spectrophotometric study of complex formation between iodoquinol (IQ) and Co 2+ , Mn 2+ , Cd 2+ , Pb 2+ , and Zn 2+ in DMF/MeOH binary mixed solvents

Adsorption of Cu 2 + , Cd 2 + , Pb 2 + and Zn 2 + onto a synthetic Mn oxide

Lotharmeyerite, Ca(Zn,Mn)2(AsO4)2(H2O,OH)2

Lotharmeyerite, calcium bis-(zinc/manganese) bis-(arsenate) bis-(hydroxide/hydrate), Ca(Zn,Mn(3+))(2)(AsO(4))(2)(H(2)O,OH)(2), is a member of the natrochalcite group of minerals, which are characterized by the general formula AM(2)(XO(4))(2)(H(2)O,OH)(2), where A may be occupied by Pb(2+), Ca(2+), Na(+), and Bi(3+), M by Fe(3+), Mn(3+), Cu(2+), Zn(2+), Co(2+), Ni(2+), Al(3+), and Mg(2+), and X ...

Cytotoxicity of Fe 2 + , Fe 3 + , Hg 2 + , Mn 2 + , Cd 2 + , Mg 2 + , and Pb 2 + to Pc - 12 Cells

Previous studies have indicated that heavy metal exposure can have an effect on the central nervous system. However, research has been inadequate to fully support this claim. The aim of this work was to determine the toxic effects of heavy metal ions including Fe, Fe, Hg, Mn, Cd, Mg, and Pb on nerve cells (e.g. PC12). PC12 cells were incubated with the metal ions at four concentrations, i.e. 12...

Measurement of Selected Thermophysical and Viscosity of Binary Mixtures of Nitromethane with 2-Propanol, 2-Butanol and 2-Pentanol

The density and viscosity values at T= (293.15 to 323.15) K for binary mixtures of nitromethane with 2-propanol, 2-butanol and 2-pentanol were measured over the entire composition range. From the experimental data, excess molar volumes, thermal expansion coefficients, excess thermal expansions, partial molar volumes at infinite dilution and deviations in viscosity were calculated. The results w...

A Study on the Extraction of Cd(II), Co(II) and Ni(II) Ions by Bis(2-ethylhexyl)phosphoric Acid and 2-Thenoyltrifluoroacetone

Keep in mind the importance of cadmium, cobalt and nickel ions as environmentally and economically strategic heavy metals, the application of two acidic extractants, named bis(2-diethylhexyl)phosphoric acid (DEHPA) and 2-thenoyltrifluoroacetone (HTTA), was assessed for the extraction-recovery of these ions from leached solution of spent rechargeable Ni-Cd batteries. The conditions for leach...
