✦ Synopsis

ELECTROGENERATED TITANOUS ION by C\_4r I)II\_TS~ dcvclopcd u similar method, escept that solicl cadmium amxlgarn was used for tltc preliminary reduction and ctcctrogencrattd ctric ion tvas used for the titration of the ferrous ion produced by aclding csccss ferric ion to the reduced uranium solution. 'I'hcsc authors wc'rc intcrcstccl in determining uranium in the 10~ milligram ant1 microgram range, and in view of the very small cluantitics the performance of both methods was quite satisfactory.
It is possible that these methods could be adapted to macro amounts of uranium. However, direct titration of -t-G uranium to the --t-d state kth an cl~.c trogcncrated reductnnt is more attractive in Ixinciple hecausc it entails fewer sources of&i-or, and it is simpler in practice. In this study such a direct titration hr~sbecndcveloyed,usingelectrogcneratcd titanous ion as the reductant and potentiometric end-point detection.
