本课题还将阿斯巴甜分别与Zn(NO_3)_2·6H_2O、CuSO_4·5H_2O、Ca(NO_3)_2·4H_2O进行了螯合反应，并且用有机溶剂沉淀法对螯合物进行了分离纯化。

The results showed that monocarboxylic acid stearic acid played a role of surfactant, and the product was still orthorhombic Ce2O(CO3)2·H2O with a high crystallization degree. In turn, duality-carboxylic acid tartaric acid...

实验结果表明在尿素及硝酸铈的混合溶液中分别加入一元羧酸硬脂酸，二元羧酸酒石酸和三元羧酸柠檬酸时，一元羧酸硬脂酸在混合溶液中只起表面活性剂的作用，其产物为斜方晶系的单晶Ce2O(CO3)2.H2O微粉，且表面活性剂硬脂酸的加入使得晶体的晶化程度明显提高；而二元羧酸酒石酸与三元羧酸柠檬酸在均相反应中则起螯合剂的作用，分别与Ce3+形成螯合物酒石酸铈和柠檬酸铈，这些结果的造成是由于其反应机理的不同所导致的。

The literature about the synthesis of the ion exchange and chelating adsorbents used in the off-line separation and preconcentration of the noble metals and the development of the on-line microcolumn separation and preconcentration of the noble metals were reviewed. Four silica gel-based adsorbents with rhodanine, 2-mercaptopyrimidine, 2-mercaptothiazoline and isophenylthiourea as the functional groups were first synthesized and applied to the on-line separation and preconcentration of silver, gold, palladium and platinum for their FAAS determination.

本论文在回顾螯合吸附材料的合成及其在贵金属的离线和流动注射在线预浓集分离发展状况的基础上，首次合成了含罗丹宁、2-巯基嘧啶、2-巯基噻唑啉和异二苯基硫脲等四种以硅胶为载体的螯合吸附剂，并用于银、金、钯和铂的流动注射微填充柱在线预浓集分离、火焰原子吸收光谱分析。

It is considered that the carboxylic groups coordinate to the metal ions in four modes: monodentate, the chelating bidentate, the bridging bidentate, and thebridging-chelating tridentate.

一般认为羧酸基有四种配位方式：单齿、螯合双齿、桥联双齿和螯合桥联三齿。
