羟基聚合铝的研究在环境化学中具有重要作用。自然条件下存在的无机单核铝本身具有毒性,而多核铝是比单核铝更毒的铝形态,它们很容易进入人体和植物产生毒害作用。因此,水解聚合铝形态研究一直是环境化学、地球化学和材料催化等众多研究领域的前沿热点课题。本文综述了在新环境材料开发中羟基聚合铝晶体研究的进展,对已获得表征的典型羟基聚合铝的结构特点进行了对比与评述,讨论了不同羟基聚合铝晶体的科学意义和应用价值。
The study of hydroxyl polyaluminum plays an important role in environmental chemistry. Inorganic monomeric aluminum, which is present under natural conditions, is itself toxic, whereas polynuclear aluminum is a more toxic form of aluminum than mononuclear aluminum, which can easily enter the human body and cause plant poisoning. Therefore, the study on the morphology of hydrolyzed polyaluminum has been a frontier hot topic in many research fields such as environmental chemistry, geochemistry and material catalysis. In this paper, the progress of hydroxyl polymeric aluminum crystals in the development of new environmental materials is reviewed. The structural characteristics of the typical hydroxyl polymeric aluminum have been compared and reviewed. The scientific significance and application value of different hydroxyl polymeric aluminum crystals are discussed.
