${it N}$,${it N}$-dialkylamides (monoamides) have been proposed as alternative extractants to tri-${it n}$-butyl phosphate in the development of spent nuclear fuel reprocessing. Although quantitative evaluation for two-phase separation between nitric acid and monoamides is required for applying monoamides to reprocessing, such evaluation has not been reported. In the present study, the property of two-phase separation between nitric acid and monoamides diluted with dodecane were measured using a turbidimeter. The obtained results showed that the two-phase separation between nitric acid and monoamides was classified into a rapid separation step and a slow separation step, and the time required for the two-phase separation increased with increasing the monoamides concentration. Those results suggested that the turbidity measurement was useful as a method for evaluating a two-phase separation quantitative property.
