Abstract: Desorption kinetics of arsenite- and arsenate-loaded Natural Laterite (NL) is performed under varying NaOH concentration (0.05-0.3 mol/L) and pH (4.0-11.0) of the desorption medium. The kinetic desorption data are well fitted to pseudo-second order kinetic model. The leaching of NL under aqueous medium is performed in the pH range of 2-12. Separately arsenite- and arsenate-loaded NL is leached according to Toxicity Characteristic Leaching Procedure (TCLP) protocol. However, recent studies indicate that TCLP significantly underestimate the leaching behaviour of arsenic. So, arsenic leaching from arsenic-loaded NL is conducted under synthetic leachate condition and results are compared with TCLP results. © 2010 Inderscience Enterprises Ltd.
