Studies on the extraction of uranium (VI) by bis(hexylsulfinyl)ethane

Studies on the extraction of uranium (VI) by bis(hexylsulfinyl)ethane 1 first-author 2 1 1 1 School of Chemistry and Chemical Engineering, Shandong University, Jinan 250100; School of Chemistry and Chemical Engineering, Shandong University, Jinan 250100; Editorial Department of Journal, Shandong Education Institute, Jinan 250100 Editorial Department of Journal, Shandong Education Institute, Jinan 250100 The extraction of uranium (VI) by bis(hexylsulfinyl)ethane(BHxSE) in nitric acid aqueous solution has been investigated. The extracted species appeared to be UO 2 (NO 3 ) 2 ·2BHxSE. Influences of nitric acid concentration, NaNO 3 concentration, Na 2 C 2 O 4 concentration and temperature on the extraction equilibrium were investigated and the thermodynamic functions of the extraction reaction were obtained.
