- Abstract
In this research, the potency of uranium extraction by dibutyl carbitol solvent has been investigated. The cheapness of this solvent is advantageous. Response surface methodology was applied to design the experiments and analyze the results to evaluate the effects of four effective variables, i.e., nitric acid concentration, dibutyl carbitol concentration, temperature, and mixing time to determine optimal conditions. The optimal conditions of uranium extraction were obtained at nitric acid concentration 30%, dibutyl carbitol concentration 60%, and T = 20 °C. Under these conditions, uranium extraction was 50.12%. The synergistic extraction with a mixture of dibutyl carbitol and tributyl phosphate improved to 88.42%.
