PROBLEM TO BE SOLVED : To provide Pu (plutonium) quantitative analysis method capable of quantitatively analyzing Pu by using radiation measurement such as α-ray spectrometry even in an analysis target sample solution containing much impurity elements such as Ca interrupting α-ray measurement.
SOLUTION : The Pu quantitative analysis method for quantitatively analyzing Pu in an analysis target sample solution 10 includes : an iron hydroxide coprecipitation step S101 for generating iron hydroxide coprecipitate 12 containing a rare earth element by adding rare earth compound and iron compound to the analysis target sample solution 10; a rare earth fluoride coprecipitation step S104 for generating rare earth fluoride coprecipitate 15 by adding fluoride to an iron hydroxide coprecipitate solution 13 obtained by dissolving the iron hydroxide coprecipitate 12; and a radiation measurement step S107 for quantitatively analyzing Pu by radiation measurement of a measuring sample 16 prepared from the rare earth fluoride coprecipitate 15.
