Abstract

A method for the determination of free acidity in process solutions containing hydrolyzable ions like U(VI), Pu(IV), etc., has been developed. This method involves the titration of the free acid with electrogenerated hydroxide ions to a preset value of pH after complexing the metal ions with sodium sulfate. This method can by easily automated, requires small sample volumes and gives accurate results with good precision for samples with [UI]/[acid] mole ratios ranging from 0.25 to 16.
