【摘要】 对实验室合成所得聚碱式氯化铝铁的结构、性质和应用作了研究。用超级离心机测得其分子量约为50万。通过X-射线衍射、红外光谱、²⁷Al核磁共振谱、扫描电子显微镜以及穆斯堡尔谱的综合分析后,认为该无机聚合物以分子长链为基本结构,在液态及固态产物中存在多种聚合态。废、污水的混凝试验证明它是一种高效稳定的新型净水剂。更多还原

【Abstract】 The characteristics and crystal structure of polyaluminium iron chloride（PAFC）synthesized in our laboratory were investigated. Its molecular weight measured is about 500 000. Comprehensive analyses by X-ray diffraction, I. R. S., ²⁷AlNMR, scanning microscope and M（o|¨）ssbauer spectroscopy found that PAFC is mainly composed of long molecular links. In the meanwhile, there are various types of polymerisates which exist in the solutions or crystals. It is showed that PAFC is a new type of cogulate agent with high efficency and stability by the coagulation test.更多还原
