| 摘 要： | 具30个铝原子的Al30是继Al13之后新发现的一种高铝聚合形态,与Al13类似,具Keggin结构,也被认为是聚合氯化铝(PACl)中的新型优势混凝形态。文章从PACl发展的视角,对Al30形态的合成、鉴定以及混凝作用进行了综述,并就高Al30的合成、新型Al30复合硅絮凝剂的开发以及其表征和混凝机理研究等三个方面作出了有关展望。

| Abstract: | Al30 is a new kind of polyaluminum species with 30 aluminum atoms and believed to be a new optimum coagulation species just as Al13.The synthesis,identification and coagulation of Al30 were summarized from view of PACl development.Finally,the expectation of research on PACl-Al30 were conducted from these three aspects including synthesis of Al30 with high content,new type flocculant composed of Al30 and Silicon,characterization and coagulation mechanism of this new flocculant. |
