Studies on the Sorption Characteristics of $^{90}Sr$ onto Granite and Tuff

Batch sorption experiments were carried out to investigate the sorption characteristics of $^{90}$ Sr onto domestic granite(HG) and tuff(TF) samples. The effect of three independent variables ([Sr], Vo1/Wt], [pH]) on the sorption was investigated. (Sr) played as the most significant variable for the $^{90}$ S $r^{2+}$ sorption onto HG, whereas [pH] had the greatest effect among three variables onto TF. Tuff shooed much greater sorption than granite, which ues accounted for their differences in mineralogical properties. The selectivity of $^{90}$ Sr was much lower than that of $^{l37}$Cs.s.s.
