Prussian Blue Analogues of A2[Fe(CN)6] (A: Cu2+, Co2+, and Ni2+) and Their Composition-Dependent Sorption Performances towards Cs+, Sr2+, and Co2+

<div>FT-IR spectra of (a) Cu2[Fe(CN)6], Ni2[Fe(CN)6], and Co2[Fe(CN)6] exhibit a characteristic peak of C-N around 2000 cm-1. (b) The location of the C-N vibration peak in Cu2[Fe(CN)6], Ni2[Fe(CN)6], and Co2[Fe(CN)6] is at 2099 cm-1, 2097 cm-1, and 2088 cm-1, respectively.</div>
