The experimental conditions for the extraction of thorium by using PMBP as extractant and 234Th as tracer in the nitric acid solution were investigated. Based on the experiments
a chemical procedure used for rapidly separating thorium from the natural uranium irradiated by 18O ions was developed. The r spectrum of the thorium fraction shows that the most of the reaction products
especially U
Ce and I can be completely removed by using the procedure.
