Ion exchange properties of the sodium phlogopite and biotite

Description
The ion exchange behavior of three sodium micas (phlogopite, Ward's Sci.; phlogopite, Suzorite Inc., biotite, Ward's Sci.) towards Li+, K+, Rb+, Cs+, Mg2+, Ca2+, Sr2+, Ba2+, Pb2+, Hg2+, Co2+, Cu2+, Cd2+ and Zn2+ ions has been studied. The ion exchange isotherms of alkali, alkaline earth and some other divalent cations were determined and concentration equilibrium constants as a function of metal loading and temperature were analyzed. Sodium micas exhibit high affinity for heavy alkali metals with the selectivity order Rb+ > Cs+ > K+. By studying the cesium uptake in the presence of NaNO3, CaCl2, NaOH, NaOH + KOH, HNO3 electrolytes (in the range of 0.01--6 M) it was found that sodium micas could remove cesium efficiently in neutral and alkaline media, which make them promising for certain types of nuclear waste treatment
