Abstract

A sorbent (HEC-Adip-Na) was prepared by the saponification of hydroxyethylcellulose (HEC) and adipic anhydride and then saponification with NaHCO3 to remove the Pb(II) from aqueous solution. The sorption experiments were done in batches and it was found that the uptake of targeted metal ions was mainly reliant on pH, sorbent dose, metal ions concentration, contact time and temperature. The highest Pb(II) removal was took place at pH 5.5, sorbent dose 50 mg, metal ions concentration 80 mg/L, contact time 30 min, and temperature 298 K.
