The measurement of Cs adsorption by the precipitation bands of Mn-based Prussian blue analogues (PBAs), Co-based PBAs, and Prussian blue (PB), which were spontaneously formed in agarose gel, was carried out using in situ X-ray fluorescence (XRF) spectroscopy.

The adsorption of Cs+ ions by the precipitation bands of a Mn–Fe based Prussian blue analogue that form spontaneously in agarose gel was investigated by XAFS spectroscopy coupled with SEM and XRF distribution analysis.

Stochastic, ripening-induced, periodic precipitation of Co–Fe-based Prussian blue analogues in water-glass gels was analyzed by XRF and XANES spectroscopies.
