Abstract

This study has investigated cadmium immobilization in the soil at the present of nano and micro titanium dioxid and the role of humic acid in nanoparticle stability and cadmium adsorption on nano and micro particles. The results of this study showed that in the soil contaminated with cadmium in suspension conditions, humic acid increased soluble cadmium in supernatant suspention and therfore increased cadmium availability in the soil. Modification of TiO2 nanoparticles surfaces with humic acid increases adsorption of cadmium at the nanoparticle surfaces. Also, since microparticles have reduced the soluble cadmium in supernatant suspensions and the concentration of exchangeable cadmium to a greater extend than nanoparticles, it can be concluded that the effect of microparticles in reducing available cadmium in the soil is greater than that of nanoparticles.
