Jz. Du et al., SORPTION AND DESORPTION OF RADIOSTRONTIUM ON CALCAREOUS SOIL AND ITS SOLID COMPONENTS, Journal of radioanalytical and nuclear chemistry, 203(1), 1996, pp. 31-36
The effect of different solid components of calcareous soil on the ret
ention of Sr was investigated by using batch technique and selective e
xtraction method. The sorption and desorption isotherms of Sr on the u
ntreated calcareous soil and the three treated soils were determined a
t 20 degrees C, pH 7.8 +/- 0.2 and in the presence of 0.001 M CaCl2. I
t was found that all isotherms are linear and that the sorption of Sr
on the calcareous soil can be described by a reversible sorption proce
ss and the sorption mechanism is mainly ion exchange.
