WebHere, we have proposed a novel automated method for the concurrent determination of Th (230 Th, 232 Th) and U (234 U, 235 U, 238 U) isotopes in small volumes (20 mL) of water matrices. A simple chemical separation procedure was achieved with an automatic system by employing UTEVA resin as separation material, and the final eluent was compatible …
