Online Spectrophotometric Measurements of Uranium and Nitrate Concentrations for Savannah River Site's H-Canyon

Journal Article · · Journal of Process Analytical Chemistry
OSTI ID:774855

Safe and efficient operation of the Savannah River Site's solvent extraction process for uranium purification requires accurate measurement of uranium and nitric acid concentrations. Previous operations have relied only on laboratory analysis of process samples. To improve the efficiency of the process, we have installed an online fiber optic based analyzer that uses a multiplexer and diode array spectrometer to rapidly acquire absorption spectra at multiple process locations. This paper describes the hardware and software developments we have made to handle the requirements imposed by the unique sampling methods in H-Canyon. Performance characteristics of the spectrometer are also demonstrated.
