摘要：
We studied the solvent extraction behavior of astatine and found the anomalous behavior of this element similar to radioiodine. Astatine was extracted into CS2 from acidic solution over a wide range of carrier iodine concentration. The distribution ratios of astatine were determined by measuring the γ-ray from 210 At with a Nal(TI) detector. A drastic change was observed around at 10−4 mol/l as in the case of 131 I. This tendency is well explained by the kinematics of the chemical reactions concemed.
