摘要
以一种含席夫碱结构的表面活性剂为配体 ,在 2 5℃、0 .0 1mol/L硼砂缓冲溶液中分别与Co2 +、Ni2 +、Cu2 +、Zn2 +络合 ,用紫外可见分光光度法测定了络合物的吸收光谱 ,并计算出其配位稳定常数。实验结果说明 :该新型表面活性剂配体具有较强的络合金属离子的能力 ,并形成稳定的配合物 ,其稳定性顺序为 :Ni2 +>Cu2 +>Co2 +>Zn2 +。
The Co 2+ ,Ni 2+ ,Cu 2+ ,Zn 2+ complexes of a new surfactant with the Schiff base structure were formed in borax buffer solution at 25℃, and the stability constants of the complexes were determined by spectrophotometric method. The experiment showed that the new surfactant as the ligand has strong ability to coordinate with metal ions and steadily form complexes.The stability of the complexes has following sequence: Ni2+>Cu2+>Co2+>Zn2+.
