A. Bassari et al., THE REMOVAL OF TH, CS AND SR IONS FROM SOLUTION USING GRANULATED PUMICE STONE, Journal of inclusion phenomena and molecular recognition in chemistry, 26(1-3), 1996, pp. 83-88
The removal of Sr, Cs, U and Th ions from aqueous solution by means of
natural pumice stone was studied using energy dispersive X-ray fluore
scence spectroscopy (EDXRF) as an analytical tool. The results indicat
e the usefulness of pumice powder and the removal efficiency was found
to be in order of Th>Sr>Cs ions, which is altered by the pH of the so
lution.
