Assessment of chromium fixation capacity of sandy loam soil


Author(s): V Karthika, P Thangavel, C Ponniah and M Mohamed Amanullah

Abstract: The adsorption of chromium species in soils has received much attention because of its toxicity and bioavailabilities, which are adsorption depended. There are very little studies on adsorption of chromium in sandy loam soil. Hence, this paper presents the Cr adsorption capacity of sandy loam soil under chromium spiked condition. A batch technique was used to perform cr adsorption studies. Soil samples were taken and mixed with different concentration of Cr solutions and later the amount of Cr adsorbed was estimated. The results revealed that, the highest Cr (VI) adsorption in soil was found to be 166.54μg g-1 of soil at 300μg g-1 of soil contamination. Adsorption of chromium increased with increasing concentration of Cr in supernatant solution upto 300μg g-1. When pH increases, negative surface charge of the soils increases, so there was an increased adsorption of Cr (III) being positively charged. Similarly, clay and organic matter carry negative functional groups on their surface facilitate the increased adsorption of Cr (III) in soils.
