To increase the uptake capacity of lead ions, surface of sawdust were modified into phosphate groups. The phosphorylated sawdust prepared through chemical reaction with H3PO4 (85%) showed a high uptake capacity of about 1.45 mmol Pb/g-dry mass at pH 4. The component of phosphorylated sawdust was analyzed by EDX (energy dispersive X-ray) and the increase of phosphate group was confirmed. The phosphorylated sawdust had a high uptake capacity at low temperature of 10 ℃ and could remove lead ions of about 98% with 0.04 g of modified sawdust. Also, most of adsorption of lead ions was completed within 40 min.
