摘要
以穆斯堡尔谱为手段,对与二价锡盐进行离子交换的天然丝光沸石以及交换前后的盐溶液烘干样品进行了研究,分析了锡离子的价态.发现天然丝光沸石对进入其孔道内的Sn^(2+)具有氧化作用.以及天然丝光沸石能够催化氧化SnCl_2 ·2H_2O饱和水溶液中的Sn^(2+),而不能催化氧化SnSO_4饱和水溶液中的Sn^(2+).
Study has been cenducted to the natural mordenite ion-exchanged with Sn2+ salt solution and the dried samples of Sn2+ salt solutions before and ofter ion-exchanging by Moss6auer spectrcum. The value states of tin ions has been analyzed.
