Sodium, rubidium and cesium ions adsorption by Prussian blue(PB)

Abstract

Abstract:The adsorption of alkali metal ions onto prepared Prussian blue (PB) was investigated in single-element solutions. The released quantities of K + constitutive of PB were measured in course of adsorption time. Acidification occurred in these solutions because of decrease in pH values after adsorption. The PB was examined by Energy dispersive spectroscopy (EDS) technique. The results showed that the equilibrium adsorption capacities was in the sequence Cs + > Rb + > Na
