摘要:

铝水解聚合形态长期以来是分析化学、材料科学、农业科学、地球化学、环境科学和生物毒理学等众多领域研究的前沿。 铝形态主要分为3种形态: 单体羟基形态、聚合羟基形态、溶胶或凝胶形态。 现今主流铝形态分析研究方法有Al-Ferron逐时络合比色分光光度法、27Al核磁共振(27Al NMR)法和电喷雾电离质谱(ESI-MS)。 铝聚合形态中Keggin结构的聚十三铝(Al13)、聚三十铝(Al30)形态具有高正电荷密度和高稳定性等优点,对无机高分子混凝剂开发具有重要意义。 本文介绍了铝水解形态分布、铝形态主要分析方法以及铝水解聚合机理,总结和归纳了Al13和Al30形态的形成机理及其应用,并对铝水解-聚合未来研究方向进行了展望。

Abstract:

The study of aluminum hydrolysis and polymerization forms has long been at the forefront of research in numerous fields, including analytical chemistry, materials science, geochemistry, environmental science and biotoxicology. Aluminum species are primarily categorized into three forms: monomeric hydroxyl species, polymeric hydroxyl species, and sol or gel species. Currently, the mainstream analytical methods for studying aluminum species include the Al-Ferron timed complexation colorimetric spectrophotometry, 27Al nuclear magnetic resonance spectroscopy (27Al NMR), and electrospray ionization mass spectrometry (ESI-MS). Among the polymeric aluminum species, the Keggin-structured polyaluminum chloride (Al13) and polyaluminum (Al30) species are particularly notable for their high positive charge density and stability, which hold significant importance for the development of inorganic polymer coagulants. This paper provides an overview of the distribution of aluminum hydrolysis species, the primary analytical methods for aluminum species, and the mechanisms of aluminum hydrolysis and polymerization. It also summarizes the formation mechanisms and research progress in the applications of Al13 and Al30 species, while offering insights into future research directions in aluminum hydrolysis and polymerization.

Key words: Aluminum hydrolysis-polymerization, Aluminum form analysis, Al13, Al30
