Abstract
The differences between the solvent extraction of Tb(III) and Tb(IV) p eriodate complexes with quaternary amine were studied carefully for th e first time. The effects of extractant concentration, phase ratio, th e pH value of stock solution, salting-out agent, extractant form, dilu ent, and extraction time were comprehensively investigated. Under opti mal conditions the separation factor between Tb(IV) and Tb(III) period ate complexes is over 5.5.
