In this work, the optimization of a segregation method of 129I and 14C, two long-living radionuclides, main constituents of nuclear radioactive waste, has been developed. To be able to carry out this project, a fractional factorial experimental design was applied using 5 factors and 2 levels by factor (25–2). Only 8 experiments were necessary to identify the variables affecting the process, and very good recoveries of both radionuclides were obtained: (94 ± 2)% for 129I, and (99 ± 1)% for 14C. The segregation of 129I was influenced by flow (Q), volume of H2SO4 (VH+), and carriers (CR), while VH+ and time (t) played a major role in the segregation of 14C.
