The application belongs to the technical field of spent fuel reprocessing analysis, and particularly relates to a method for rapidly measuring the content of oxalate in radioactive liquid. The method comprises the following steps: adding different volumes of tri-n-octylamine, and obtaining an organic phase sample after extraction; measuring the maximum absorption wavelength of oxalate ions, the optimal sample injection amount and flow rate, and the optimal extraction agent proportion; preparing a series of oxalate standard solutions with different concentration gradients, and measuring the peak area and concentration relationship of the standard solutions under the optimal conditions; and taking a certain amount of pretreated sample, and measuring the sample under the optimal conditions. The application uses tri-n-octylamine to extract and separate oxalic acid to obtain a pretreatment method, simplifies the complex pretreatment steps of oxalate measurement, shortens the sample measurement time, measures the content of oxalate in the post-treatment process sample on a liquid chromatograph, and realizes the effects of rapidness, accuracy, safety and the like.
