Hydrous titanium oxide of good column quality was prepared from a solution of titanic chloride by precipitation with ammonia. The composition of the exchanger was ascertained by TGA to be TiO{sub 2}{center dot}0.73H{sub 2}O with an IEC value 0.29 meq/g. Study on the uptake of 21 tracer cations over titania showed high adsorption for many cations. Radiochemical separations of carrier-free {sup 125m}Te and {sup 132}I from {sup 125}Sb and {sup 132}Te, respectively, have been carried out on a titania exchanger column by applying very simple chemical procedures. Radionuclidic purity of the separated products {sup 125m}Te and {sup 132}I were ascertained by {gamma}-ray spectrometry. Overall separation procedures took less than half an hour, and the yields were quantitative.
