摘要：

Solvent extraction of uranium(VI) from aqueous solutions of ammonium thiocyanate has been investigated in the presence of dibenzo-18-crown-6. Uranium(VI) was quantitatively extracted from 1.0M ammonium thiocyanate using 0.01M dibenzo-18-crown-6 in nitrobenzene. Back extraction of U(VI) was quantitative with various stripping agents. Separation of U(VI) from other elements was achieved from binary as well as multicomponent mixtures. Uranium was determined in monazite sand and syenite rock samples. The method is very simple. rapid and highly reproducible (approximately +/-2%).
