Nickel (II) sorption on porous ZnO prepared by solution combustion method

Water effect on the combustion preparation of ZnO is presented. The obtained materials were characterized through their specific surface area, morphology, particle shape and fractal dimension. They were tested in Ni2+ sorption. The surface fractal dimension of the combustion prepared sample was 1.9 but in those where water was included it decreased to 1.8. In the sample prepared by calcination it was 2.1. A linear correlation between the fractal dimension and Ni2+ sorption was found.
