Effect of Mg ions on competitive metal ions adsorption/desorption on magnesium ferrite: Mechanism, reusability and stability studies.

The adsorption behavior of magnesium ferrite in single- and multicomponent metal ions solutions in the presence of Mg ions were studied. A dramatic decrease in the adsorption capacity of magnesium ferrite towards Mn, Co, and Ni ions for comparison study of single- and multicomponent solutions was established. The affinity of the sorbent in accordance with the maximum sorption capacities increases in the following order Cu > Co > Ni > Mn.

Use of chicken feather and eggshell to synthesize a novel magnetized activated carbon for sorption of heavy metal ions.

Keeping environment and sustainability concept in view with preparation of new sorbents, two waste by-products from the poultry industry, i.e. feather and eggshell, were used for synthesis of a new magnetic activated carbon for sorption of heavy metal ions.

SnO Nanostructures: Effect of Processing Parameters on Their Structural and Functional Properties.

Zero- and 1D (one-dimensional) tin (IV) oxide nanostructures have been synthesized by thermal evaporation method, and a comparison of their morphology, crystal structure, sorption properties, specific surface area, as well as electrical characteristics has been performed. Synthesized SnO nanomaterials were studied by X-ray diffraction, scanning and transmission electron microscopy (SEM and TEM), N sorption/desorption technique, IR spectroscopy and, in addition, their current-voltage characteristics have also been measured. The single crystalline structures were obtained both in case of 0D (zero-dimensional) SnO powders and in case of 0D nanofibers, as confirmed by electron diffraction of TEM.

Magnetic Nanocomposites as Efficient Sorption Materials for Removing Dyes from Aqueous Solutions.

Magnetic composite sorbents based on saponite clays with different content of magnetite (2-7 wt%.) were synthesized. The samples were analyzed by X-ray diffraction methods, and it was found that the Fe3O4 in composites is in the nanorange.
