The potential of using quaternized rice husk (QRH) as a sorbent for the removal of As(V) from aqueous solution was investigated. Both batch and column studies were carried out. Results of batch studies indicate that sorption was pH and temperature dependent. Equilibrium was attained within 20 minutes and sorption appeared to be essentially an ion exchange process.
