A new Gemini Cationic Surfactant (GCS) was synthesized to extract and separate U(VI) ions from sulfate solution. The Gemini cationic amphipathic was synthesized by refluxing N, N, N, N-tetramethyl diethylene triamine with cetyl chloride. Traditional log D-log [GCS] analysis shows that the ligand has removed uranium as a complex of 2:1 (ligand: metal) ratio. The extraction of uranium was achieved using a new GCS extractant in octanol at pH 1.5 using 0.05 M GCS extractant from sulfate solution and the process is an exothermic process (ΔH = –10.94 kJ mol–1). Finally, El-Missikat sulfate leaching liquor was treated with optimum parameters of solvent extraction for U separation. [ABSTRACT FROM AUTHOR]
