Description
Uranium (6) extraction from hexamethaphosphate solutions by alkylamines in hexane and kerosene with the aliphatic alcohole addition is studied. Uranium is extracted as an associate with the (C17H35NH3)+ : UO22+ : P6O186- =10 : 1 : 2 ratio. Techniques of uranium concentration and extraction-photometric determination in seawater and brines are proposed. In the absence of additions uranium is determined with arsenazo 3 at pH 1.5 - 2.5, while in the presence of interfering components, with arsenazo 3 in 4n HCl. The relative error of determination does not exceed 11 %
