摘要
改进了原有的水钠锰矿合成方法,得到了单相层状水钠锰矿,并用XRD谱和SEM等方法对合成的层状水钠锰矿化合物进行了表征.结果表明,在合成过程中通过提高反应物的二价锰盐溶液浓度,可提高水钠锰矿晶体的结晶度.
An improved method was presented for the synthesis of birnessite, and single-phase layered birnessite was obtained. Birnessite samples synthesized by this method were characterized by the XRD and SEM. The results indicate that the crystallinity of the birnessite synthesized by this method is increased greatly by increasing the concentration of Mn （Ⅱ） solution.
