Abstract
The uptake of fission products 137Cs, 85Sr, 57Co, onto an antimony silicate, and its Na, K, Ca ion-exchanged forms have been studied. Distribution coefficients have been determined as a function of the concentrations of sodium, potassium and calcium nitrate solutions (0.01, 0.1 and 1M). Plots of log distribution coefficients against concentrations enabled the elucidation of exchange mechanisms in some cases. Potassium had the least, and calcium the most effect on isotope uptake when present as macro ions. The presence of sodium promoted hydrolysis that also affected the exchange selectivity.
