摘要: 将两种N-乙酸取代氮氧杂大环固载(键合)于硅胶上,制得了硅胶固载大环(SGBMC)。研究了它们与Co(Ⅱ)、Ni(Ⅱ)、Cu(Ⅱ)、Zn(Ⅱ)的配位性能、容量、选择性以及SGBMC的再生。结果表明它们对Cu(Ⅱ)有良好的配位选择性,且配位后的金属离子易为稀盐酸洗脱,SGBMC至少可重复使用5次。

Abstract: Two novel N-acetic acid substituted and covalently attached to silica gel macrocycles containing oxygen-nitrogen (silica gel bound macrocycle, SGBMC) have been prepared. The coordination capacities and selectivity properties of SGBMC towards Co(Ⅱ), Ni(Ⅱ), Cu(Ⅱ), Zn(Ⅱ) have been investigated in detail. The coordinated Co(Ⅱ), Ni(Ⅱ), Zn(Ⅱ), Cu(Ⅱ) can be easily leached out from SGBMC by dilute hydrochloric acid, and the SGBMC could be used repeatedly at least more than five times.

Key words: N-acetic acid substituted oxygen-nitrogen macrocycle, transition metal, immobilized complex, silica gel
