Abstract
The isotope dilution mass spectrometry with {sup 233}U as a single internal standard has been developed. It can be used to determine the abundant ratio precisely in the uranium sample. It is an absolute measurement method based on gravimetry. The {sup 233}U and measured uranium sample are gravimetrically mixed. Then, the R{sub 58} ({sup 235}U/{sup 238}U) and R{sub 38}({sup 233}U/{sup 238}U) in the mixture are simultaneously measured, and the R{sub 38} is taken as internal reference standard. By using the iteration operation the R{sub 58} can gradually reach to its true value. The total uncertainty of the method for measuring R{sub 58} is 0.15%. In addition, it has many advantages, such as, the measured external precision can be better than 0.02%.
