摘要
采用高锰酸钾做氧化剂,二价过渡性金属硫酸盐为还原剂,采用氧化沉淀法制得了几种过渡金属氧化物和一种铁锰钴复合氧化物.对制得的样品进行了XRD、SEM和FTIR表征.以亚甲基蓝染料为模拟废水,考察了不同过渡性金属氧化物对亚甲基蓝的催化和吸附性能.结果表明,铁锰钴复合氧化物相对于单一氧化物催化性能更为优异.
Potassium Permanganate was used as oxidant; two valence transitional metal sulfate tam, and several transitional metal oxides and a new Fe-Mn-Co composite oxide were successfully p was used as reducrepared with oxida- tion-precipitation method. The samples were characterized by XRD, SEM and FTIR techniques. Methylene Blue solution was prepared as model environmental liquid, the adsorption and catalytic properties effect of different samples on the methylene blue were evaluated. The results show that the catalytic properties of Fe-Mn-Co composite oxide is better than single oxide.
