A method comprises the step of spray-drying a slurry of potassium cobalt hexacyanoferrate (KCOHEX) particles to provide monodisperse, substantially spherical KCOHEX particles. In a further step the spherical KCOHEX particles are activated by heating until their color changes from dark green to purplish black. The particles can be used free flowing, in columns or beds, or entrapped in a porous, nonwoven, fibrous web or matrix, to selectively remove Cs ions from aqueous solutions. |
