Chitosan had been modified by polyacrylate sodium, glularaldehyde, and NaBH4, respectively, which afforded three kinds modified chitosan: polyacrylate sodium modified chitosan (CIS- PA4) chitosan bead and pentamethylene diamido crosslinked chitosan bead (CTSB- G- Hy). The adsorption properties of CTS-CTSB and CTSB-G-Hy were studied by L25(56) orthogonal experimental design. They show high adsorption activities for Pb2+ in solution. The highest removal efficiency of Pb2+ for CTS-PA4, CTSB and CTSB-G-Hy is 94%, 96% and 93%, respectively. The results showed the adsorption property of CTSB is the highest. The CTSB- G- Hy has good mechanical property, acid-resistance and alkali-resistance.
