Abstract

Abstract

Samples of the phosphate mineral crandallite, CaAl3(PO4)2 (OH)5 · H2O were equilibrated with solutions containing calcium and strontium chlorides labelled with 45Ca and 85Sr. The apparent selectivity coefficient for the equilibrium system, calculated from the isotopic dilution, varied from 1.5 at pH 9.3 to 8.2 at pH 4.7. The mineral has limited value as a scavenging agent for the removal of strontium from soil.
