Aqueous solution of N-cyclohexyl-2-pyrrolidone (NCP), which is known as a selective precipitant for U(VI), changes into two solution phases (NCP-rich and -poor phases) upon heating. Aiming at development of a new actinoid separation method utilizing NCP solutions, we investigated characteristics of NCP solutions. We found that novel phase separation method using microfluidics could be applied to NCP/water system.
