Adsorption and desorption of Sb(III) on goethite

Jianhong Xi, Sufang Zhang

Abstract

The present study examined the effect of pH and ionic strength on Sb(III) adsorption on goethite and desorption of Sb(III) binding to goethite. Adsorption of Sb(III) is favored by low pH and high ionic strength. Desorption of Sb(III) from Sb(III) treated goethite is dependent on the adsorption suspension pH and increased with increasing the original suspension pH.
