The extraction thermodynamics of uranium(Ⅵ) from nitric acid solution by N-octanoylpiperidine in toluene was investigated. The results showed that two extracted species of UO 2(NO 3) 2(OP) and UO 2(NO 3) 2(OP) 2 were formed
and the equilibrium constants were K ex1=0.538 and K ex2=4.230 respectively. Through considering the sub-reaction of extraction
the equilibrium constant of extracting nitric acid with N-octanoylpiperidine were obtained to be K HNO 3=0.097.
