摘要:

δ-MnO2的吸附和氧化反应机理表明:其表面吸附作用和对某些金属离子的氧化行为与δ-MnO2的晶体结构有很大的关系。介绍了δ-MnO2的晶体结构与制备方法,对不同制备方法的特点进行了分析。针对国内外δ-MnO2在水处理中的研究动态,介绍了目前国内外在对δ-MnO2的改性研究中常用的方法及应用情况。最后对δ-MnO2今后的发展方向进行了展望。

关键词: δ-MnO2, 水处理, 重金属

Abstract:

The mechanisms of the adsorption and oxidation reactions of δ-manganese dioxides show that the processes of surface adsorption and oxidation for metal ions are related to the crystal structures of δ-manganese dioxides. Crystal structures and preparation process of δ-manganese dioxides are introduced. Different preparation processes and characteristics are analyzed. According to the research trends of its application in water treatment in China and abroad,the frequently used methods and application situation in the modified research on δ-manganese dioxides are also introduced. At the end,the future development direction is forecast.

Key words: δ-MnO2, water treatment, heavy metal
