Description
The method described herein involves the separation of U and Pu from suitably diluted sample aliquot of the high level liquid waste solution by co-extraction with 3% trialkyl phosphine oxide (TRPO) solution in normal paraffin hydrocarbon (NPH) at 3.5M HNO3. From loaded organic phase, U is stripped with 0.8 M oxalic acid and assayed by ICP-AES whereas Pu is reductively stripped with organic soluble tertiary butyl hydroquinone (TBH) and assayed by alpha-radiometry. The reliability of the method is checked by evaluating the analytical recovery of known amount of U and Pu spiked in diluted sample aliquots. The recovery is found quantitative within the experimental errors. Results of actual HLLW samples showed good agreement between existing and present method. (author)
