| 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.

| Abstract: | 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 analyzed and the surface chemistry was characterized by many advanced analysis technology.The results showed that the hydrated manganese oxide has abundant surface hydroxyl radical and its specific surface is 219.041 m2/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. |
