Figure 3
(a) Pictures of a clear yellow K2Ba[Fe(CN)6]·2.6H2O dispersion before (left) and immediately after (right) the addition of Cs/Sr. (b) UV–Vis spectra of K2Ba[Fe(CN)6]·2.6H2O (black) and Cs2Sr[Fe(CN)6] (red). Both spectra show the characteristic features of the [Fe(CN)6] moiety (Gray & Beach, 1963  ). (c) FT–IR spectra of K2BaHCF (black) and Cs2SrHCF (red). All peaks shift to higher frequencies after ion exchange. The arrows indicate the δ(HOH) signal at 1611 cm−1 and ν(OH) signals at 3527 cm−1 and 3601 cm−1 observed for K2BaHCF but not for Cs2SrHCF. These signals indicate the presence of structural water, which is common in hexacyanidoferrate particles. (d) Enlarged view of the FT–IR spectra in the 400–650 cm−1 range. |
