- 中文摘要: The adsorption of titanium and zirconium on Amerlite-IR 120 and the elution curves at various acidities have been discussed. The elution curves of zirconium were found to change in an irregular manner, while those of titanium in a regular manner at acidities ranging from 0.75 N to 1.25 N. the abrupt change of amount of titanium and zirconium eluted with the eluate volume furnished a strong support to the view of change of ionic species. By using 0.75N sulfuric acid as an eluent, the author has succeeded in separating a mixture of titanium and zirconium. The results showed that more than 90% of titanium-free Zirconium could be isolated by a single elution.
