| 英文摘要 | crosslinked chitosan was modified with 4-amino-4'-nitroazobenzene and characterized by ft-ir and sem. the adsorption of au(iii) and pd(ii) was optimum at ph 3.0 for au(iii) and at ph 2.0 for pd(ii), where maximum mass adsorption were 69.93 mg g(-1) and 58.58 mg g(-1), respectively. the adsorption isotherms obey the langmuir equation in case of au(iii), and the freundlich and langmuir equations in case of pd(ii). the adsorption kinetics follows a pseudo-second-order model. this new adsorbent shows high affinity for au(iii) and pd(ii), while the adsorption is negligible for k , na and ca and no adsorption of several other metal ions occurs. the method was successfully applied to the determination and separation of au(iii) and pd(ii) in aqueous samples and ore. |
