摘要

以氨基酸l-色氨酸(l-色氨酸)、1,2-双(4-吡啶基)乙烯(bpe)和Zn2+、Co2+和Ni2+离子为原料，分别制备了{[Zn(L-trp)(bpe)(H2O)]·2H2O·2NO3}n、{[Co(L-trp)(bpe)(H2O)]·H2O·NO3}n和{[Ni(L-trp)(bpe)(H2O)]·H2O·NO3}n三个金属有机骨架。采用x射线衍射(XRD)、热重分析(TGA)和差示扫描量热法(DSC)对所得晶体进行了表征。对合成材料从水溶液中吸附钌进行了检测。在这一系列的金属有机骨架中，只有ni化合物适合进行吸附实验。

L-Tryptophan metal-organic frameworks based on transition metals: Preparation, characterization and application for ruthenium3+ ions sorption

Three metal-organic frameworks, {[Zn(L-trp)(bpe)(H2O)]·2H2O·2NO3}n, {[Co(L-trp)(bpe)(H2O)]·H2O·NO3}n and {[Ni(L-trp)(bpe)(H2O)]·H2O·NO3}n were prepared from amino acid L-tryptophan (L-Htrp), 1,2-bis(4-pyridyl)ethylene) (bpe), and the Zn2+, Co2+ and Ni2+ ions respectively. The obtained crystals were characterized by X-ray diffraction (XRD), thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). Synthesized materials were checked for sorption of ruthenium from aqueous solutions. From this series of metal-organic frameworks, only Ni-compound is suitable for the adsorption experiments.
