Concentration Levels

Extraction of nitric acid from aqueous solutions to tributyl phosphate-kerosene solvents has been studied in the concentration regions 2-6 kmol m-3 of nitric acid and 0.5-2 kmol m-3 of tributyl phosphate. At these concentration levels, the transfer process is greatly enhanced by interfacial turbulence. This effect was taken into account by the model suggested for the mathematical description of the extraction kinetics.
