Interlayer K from biotite was extracted with sodium tetraphenylboron for varying time intervals. Then, the Cs sorbed from 10 ‐4 N and 10 ‐6 N CsCl solutions by the original biotite and its altered products was determined. The increased removal of K successively increased the vermiculite component with expanded 14A lattice and a larger CEC and decreased biotite with a collapsed 10A lattice and a smaller CEC. Further, the greater the amount of vermiculite and larger the CEC, the more was the Cs sorbed. Obviously, the expanded component with a larger CEC sorbed more Cs than its collapsed counterpart. These sorptions by mixtures of biotite and vermiculite, thus, do not support the contention that Cs is sorbed selectively by minerals with a 10A lattice spacing.
