Solvent Extraction Studies of Uranium (VI) from Aqueous Media into Chloroform Solution of N,N´-ethylenebis(4-propionyl-2,4-dihydro-5-methyl-2-phenyl-3H-pyrazol-3-oneimine)

U. J. Chukwu & J. Godwin · Chemical Science International Journal · 2013

The extraction of Uranium (VI) from aqueous media of varying pH values (0.3 – 9.0) was studied using chloroform solution of 0.05M N,N`-ethylenebis(4-propionyl-2,4-dihydro-5-methyl-2-phenyl-3H- pyrazol-3-oneimine) (H2PrEtP) Schiff base. The effect of 4-propionyl-2,4-dihydro-5-meth...
