| 中文摘要 | In the current study, the adsorption behavior of N-succinyl-chitosan (NSC) for Cu(II) ion was investigated. The equilibrium adsorption data of NSC have been found to fit the Langmuir adsorption isotherm, and the saturation adsorption capacity is 2.74 mmol/g. Based on the obtained optimum condition of the influences of the pH, the adsorption temperature and time, the degree of substitute (DS) of NSC and the dosage of crosslinking agent, a new perfect adsorbent material, crosslinked NSC resins with Cu(II) as templateions (crosslinked NSC template) was synthesized. The adsorption experiments indicated that the crosslinked NSC template and NSC can selectively adsorbed Cu(II) ions from the solution of Cu(II), Zn(II), Co(II), and Ni(II) ions coexistence, but the selectivity of the crosslinked NSC template is higher than that of NSC. Furthermore, the crosslinked NSC template has shown a good reusability. The FTIR analysis results revealed that the adsorption sites mainly occur on the carboxyl groups of the succinyl groups of the crosslinked NSC template in the Cu(II) adsorption process. |
