螯合

The result showed that HWG possessed antioxidative characteristics including α,α-diphenyl-β-picryl hydrazyl, 2,2'-azino-bis (3-ethylbenzthiazoline -6-sulphonic acid) and superoxide anion radical-scavenging effects, Fe2+-chelating ability, reducing power and lipid peroxidation inhibition.

随著HWG浓度的增加，其清除自由基包括superoxide anion radical、α，α-diphenyl-β-picryl hydrazyl、2，2'-azino-bis (3-ethylbenzthiazoline-6-sulphonic acid 、还原力与螯合亚铁能力也随之增加，且HWG清除超氧阴离子及螯合亚铁的效力优於标准品Vit C与Trolox。

But it is able to obtain mixed LB films of metallorganic complexes and long-chain fatty acids by taking advantage of their intermolecular interactions.

And utilize organic solvent separate and purify aspartame metal complex.As ferrous salt easily oxidized into three price molysite.

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 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。
