DETERMINATION OF ENRICHED URANIUM IN PROCESS WASTE STREAMS

摘要

An indirect colorlmetric method, adaptable to in-line application, was demonstrated for the measurement of enriched uranium in waste from tributyl phosphate solvent extraction processes. The maximum absolute error from process variables was 10-6M uranium over a uranium concentration range of 10-6 to 10-5M. The necessary sensitivity for the analysis of waste containing this low concentration of uranium was obtained by selecting as the sample the organic solvent in contact with the aqueous waste.
