Removal of Nickel and Cadmium from Aqueous Solution using Carbonaceous Magnesium Oxide: Thermodynamic and Kinetic study.

Generation and entrance of toxic materials to aqueous environment causes many problems human health. In the current study, removal efficiency Cd (II) Ni(II) from solution was investigated by carbonaceous magnesium oxide. Three types C-MgO adsorbents were synthesized via pyrolysis prepared complex Mg(acac)2 at three temperatures. Fabricated characterized XRD, SEM, BET. XRD results revealed that consist only oxide carbon phase without any impurities. SEM technique used characterizes surface morphology samples. N2 adsorption-desorption isotherm calculate BET area The had a good agreement with measurement which improved high temperature increase particles size reduce area. adsorption studies showed oxides have effeciency for removalfrom kinetically follow pseudo-second order model.
