Influence of gamma-radiation on the ionic liquid [C4mim][PF6] during extraction of strontium ions.
The preliminary results presented here show that gamma-irradiation of ionic liquid 1-butyl-3-methylimidazolium hexafluorophosphate ([C4mim][PF6]) markedly decreases Sr2+ partitioning in the crown ether/[C4mim][PF6] extraction phase due to the competition between radiation-generated H+ and Sr2+ to interact with the crown ether, however, washing irradiated [C4mim][PF6] with water gives a simple way of recycling the ionic liquid.
