Indium and Thallium Extraction into Betainium Bis(trifluoromethylsulfonyl)imide Ionic Liquid from Aqueous Hydrochloric Acid Media

Carrier-free In and Tl radionuclides were extracted into a protic ionic liquid [Hbet][Tf2N] from HCl media with and without the presence of zwitterionic betaine in the aqueous phase.
