Abstract
A laboratory study was conducted to investigate the ability of modified silica gel for the removal of arsenate from synthetic arsenate solution. The silica gel was modified by the standard procedure and was characterized by SEM, FTIR, Chemical analysis and XRD. To know the practical applicability, a detailed removal study of arsenate ion was undertaken. The removal of arsenate was 99.87% under neutral condition and using 0.3 gm of adsorbent in 100 ml of arsenate solution having initial concentration of 1 mg/L.5mg/L,10 mg/l,50 mg/L respectively. The percentage removal increases with increase in pH till it reaches 5.0 then decreases. The process was rapid and equilibrium reaches within first 45 minutes.
