Reactivity of Pb(II) at the Mn(III,IV) (oxyhydr)oxide--water interface.
In this study, the reactivity of lead (Pb(II)) on naturally occurring Mn(III,IV) (oxyhydr)oxide minerals was evaluated using kinetic, thermodynamic, and spectroscopic investigations. Aqueous Pb(II) was more strongly adsorbed to birnessite (delta-MnO1.7) than to manganite (gamma-MnOOH) under all experimental conditions. The isoteric heat of Pb adsorption (delta HT) or birnessite was 94 kJ mol-1 ...
متن کاملAdsorption and Precipitation of Aqueous Zn(II) on Hematite Nano- and Microparticles
As part of a study of the effect of particle size on reactivity of hematite to aqueous metal ions, the sorption of Zn(II) on hematite nanoparticles and microparticles was examined over a wide range of Zn(II) concentrations using Zn K-edge EXAFS. When reacted with nanoparticles at pH 5.5 and low Zn(II) sorption densities (0.04 < Γ < 2.76 μmol/m), Zn(II) formed five-coordinated or a mixture of fo...
متن کاملSynthesis and characterization of Nickel (II) Chloride nanoparticles with the study of their thermal behavior
In this research nanoparticles of Nickel (II) Chloride were synthesized and characterized using fourier transform infrared (FT-IR) spectra. Nanoparticles of Nickel (II) Chloride were prepared by using of ball mill device. A ball mill is one kind of grinding machine, and it is a device in which media balls and solid materials (the materials to be ground) are placed in a container. In the researc...

متن کاملSolid state synthesis of NiO nanoparticles from [(1,2-bis(2-formyl-3-methoxyphenyl)propane)nickel(II)] chloride
In this paper, nickel oxide (NiO) nanoparticles have been prepared by solid state thermal decomposition of an acyclic nickel(II) complex (1,2-bis(2-formyl-3-methoxyphenyl)propane)nickel(II) chloride, [NiL]Cl2, in an electrical furnace at optimal temperature, 450 ºC for 3.5 h. The nickel(II) complex is obtained via solid state synthesis using nickel(II) chloride and tetradentate O4 acyclic ligan...
