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 gamma-ray from 210 At with a Nal(T1) 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 concerned.
