Experimental investigation of uranium extraction from the industrial nuclear waste treatment plant by tri-butyl-phosphate

With the main object of reducing nuclear waste materials, in this study, numerous influential factors were optimized to find the best conditions for uranium extraction from a nuclear waste using Tri-butyl-phosphate extractant. The optimum dissolution point of solid waste was obtained at 0.01 mol L−1 nitric acid, ambient temperature, and pH value of 5.7. The results showed that the extraction efficiency is increased by increasing the acid concentration, extractant concentration, mixing time, and organic to aqueous phase ratio. The phosphoric acid was selected as the most suitable option with an extraction efficiency of 76% and a distribution coefficient of 3.3.
