Abstract

In this study, some factors affect cadmium adsorption onTiO2 nanoparticles in soil and stability of nanoparticles in soil suspensions have been investigated. The results of this study showed that in soil contaminated with cadmium in suspension conditions the amount of cadmium stabilized by nanoparticles, which is attributed to adsorption of cadmium on surface of the nanoparticles, will depend on soil to water ratio (1:20, 1:10 and 1: 5), amount of soil pollution cadmium (5 and 10 mg of cadmium per kg of soil) and the use of nanoparticles (zero, 5.0, 1, 5%). So that the least amount of Cd-DTPA was found in soil to water ratio of 1: 5 and 5% of nanoparticles and in the soil contamination level of 10 milligrams per kilogram of cadmium. Also the results of stability tests indicated that the stability of titanium dioxide nanoparticles in soil suspensions over the ten days of release was comparable with that at the beginning of addition of nanoparticles, is good. In total, considering the fact that immobilization of cadmium in soils is a technique to improve the quality of soil and titanium dioxide nanoparticles showed proper stability in soil suspensions, it becomes evident that the use of nanoparticles in the decontamination of calcareous soils is appropriate.
