Abstract: This article mainly state the preparation and the adsorption properties of N-Succi- nly-chitosan.The chitosan is prepared by chitin by myself,and the DAC is determined with acid-base titration. N-Succinly-chitosan was prepared via the ring-opening reaction of succinct anhydride with chitosan in dimethyl sulfoxide.The sample was characterized by IR spectra toexplain the N-Succinly-chitosan’s structure.The adsorption properties of N-Succinly-chitosan to Cu(II) Pb(II) Ni(II)ion were investigated.The influence of the amount of N-Succinly-chitosan and the concentration of metal ions,the pH value in solution and adsorption time was discussed.It is found that the concentration of metal ions and the pH value in solution influence more to theadsorption property of N-Succinly-chitosan.
