COEXTRACTION OF URANIUM AND TECHNETIUM IN TBP-SYSTEMS

Abstract
The coextraction of technetium with uranium in TBP/HNO systems has been studied. The extraction mechanism, has been found to agree well with experimental data at 5 M HNO,.The extraction constant, KTC,e for this reaction Is given by where T is temperature (K) and CT total TBP concentration (%). This equation is valid for 5 M HNO, DSFS–30% TBP, and from 20 to 60°C, with an average error of 2·8% in log KTC,e
