One is the interstitial water or zeolitic water, it corresponds to the broad absorptive band at around 3498 cm〓 that results from the association of water owing to the H-bonding. 2 The other is the water coordinated to lanthanum, corresponding to the very strong sharp peak at 3607cm〓, The peaks at around 1600cm〓 were assigned to the bending vibrations of water in LaHCF, two sharp peaks were found at 1601cm〓 and 1624cm〓 respectively, which correspond to two bending vibrations of the interstitial water and the coordinated water respectively in the structure of LaHCF.

通过电化学扫描法，得到了一种有电活性的稀土元素化学修饰电极—铁氰化镧修饰电极；并用循环伏安法进行了表征，比较了碱金属离子Li〓，Na〓，K〓，Rb〓，Cs〓和H〓在膜中的通透性，结果表明氢离子能透过铁氰化镧膜而碱金属离子则不能透过铁氰化镧膜；稳定性研究表明，该修饰电极在纯1.0mol/L HCl溶液中扫描，峰电流迅速下降，到第10圈时峰电流几乎为零，而在混合溶液1.0mol/L KCl+0.10mol/L HCl。
