The performance of a fixed bed column for the removal of As(III) from aquatic environment was studied. Laterite soil was used as the adsorbent material. The column with 2-cm diameter, different bed heights such as 10 cm, 20 cm and 30 cm could treat 1.3 l, 7.9 l and 14.88 l, respectively, of As(III)...
