Automatic control of uranium and nitric acid in reextraction solutions

New indirect potentiometric method on the basis of two ion-selective electrodes EM-NO3-01 and ESL-43-07 is proposed for semultaneous determination of uranium and nitric acid under dynamic conditions. Application of the method with the simpliest equipment makes it possible to determine uranium and nitric acid with relative average quadratic deviation << 0.03. Area of uranium concentrations determined ranges from 59 to 117 g/l and of nitric acid - 2.5 to 4.1 g/l. Transducer for continuous automatic control of uranium and nitric acid in reextraction solutions is created on the basis of the studies performed
