This paper summarizes the results of the coprecipitation of ultramicrogram uranium with Fe(OH)₃ from saturated NaCl solution and separation of uranium from Fe(Ⅲ) by solvent extraction with TBP as extractant. In the first step, the coprecipitation efficiency of uranium is more than 95%; in the second step, extraction percentage of uranium is more than 98%, and stripping efficiency of uranium is nearly 100% (twice stripping) and separation factor (separation of Fe(Ⅲ) from uranium) is more than 10³.
