| Abstract | A medium known as sulfate modified iron oxide coated sand (SMIOCS) was evaluated for the removal of As(III) from symthetic water with ionic strength of 0.01M NaNO3 employing fixed bed mode. The medium was characterised for BET surface area; alkali and acid resistance; and presence of iron, barium and sulfur on sand surface. The particle size of media shown significant impact on bed volume treated with similar experimental protocol. A theoretical model, Wolborska model, has shown good correlation with observed experimental data generated during depth variation studies at flow rate of 1.56 m(3)/m(2) /hr with influent As(III) concentration of 1.0 mg/L. Regeneration studies using 0.2 M NaOH as regenerant resulted in nearly 83% recovery of As(III) during up flow mode. |
