中文摘要：

以制备的无定型水合氧化锰对实验室配水进行了混凝试验研究,探讨了其在给水处理中应用的可行性;采用多种分析测试技术从粒子的化学组成、比表面积、界面官能团特征、粒子的物相等方面对该水合氧化锰粒子进行了表征。研究表明：该水合氧化锰粒子具有丰富的羟基化表面,比表面积为219.0411 m2/g,是一种无定型水合物,表现了优良的吸附污染物的界面特性;低投量（2 mg）的该水合氧化锰对于实验室配水具有优良的混凝性能,特别适用于高浊度原水的混凝处理。

英文摘要：

Coagulation experiments to the simulated raw water were carried out in laboratory scale with the amorphous hydrated manganese oxide and the feasibility in treating diet water as a new purifying agent was studied. The composition was analyied and the surface chemistry was characterized by many advanced analysis tech- nology. The results showed that the hydrated manganese oxide has abundant surface hydroxyl radical and its specific surface is 219. 041 m^2/g. It belongs to amorphous MnO2. It exhibits surface chemistry of excellent removal pollutants and gives best coagulation efficiency to the simulated raw water in a low dosage （2 mg）. It is adaped to treatment of raw water with high turbidity especially.
