Abstract

Octadecyl silica cartridge modified with Cyanex302 was used for the separation and preconcentration of thorium (IV) and uranium (VI) from aqueous solutions. The influences of analytical parameters including pH, and the amount of Cyanex302 were investigated on the adsorption of analyte ions. The maximal capacity of the cartridges modified by 30mg of Cyanex302 was found to be 20 mg/L of uranium and thorium.
