| 摘要: 近二十年来,高分辨率27Al核磁共振(27Al NMR)广泛应用于研究Al(Ⅲ)离子水解过程,Al(Ⅲ)与环境生物配体的配位化学,环境与生物样品中铝含量测定和形态分析,监测铝在植物、动物、酵母菌等微生物中的转运过程,具有快速、直接、非破坏性等优点。27Al NMR不仅适用于高浓度的溶液,也可应用于低浓度(10-6mol·L-1)的实际环境、生物样品。应用27Al MASNMR可直接对固态样品中铝的存在状态和含量进行表征和测量。本文中对27Al NMR的应用进展作一评述,并总结了近二十年来文献发表的27Al化学位移数据。引用文献70余篇。 |

| Abstract: 27Al nuclear magnetic resonance(NMR) spectroscopy, as a rapid, direct and non destructive analytical tool, has been used to investigate the hydrolysis process of aluminum(Ⅲ) in the presence and absence of other organic and inorganic ligands, to study the structure and reactivity of aluminum(Ⅲ) complexes with environmentally and biologically important ligands, to quantitatively determinate different aluminum(Ⅲ) species present in environmental and biological samples and to monitor the transport process of aluminum in plants, animals, yeast and other organisms during the last twenty years. It can deal with not only the high aluminum content solutions but also the natural dilute (10-6mol·L-1) aluminum(Ⅲ) samples from the environment and biological materials. 27Al MAS NMR can characterize and determinate aluminum in the solid samples. In this paper, the advances of these applications were reviewed and a lot of 27Al chemical shift data of species present in aqueous solution were collected. More than 70 references were cited. |
