Abstract
The extraction behavior of Zr(IV), Ce(III), Th(IV) and U(VI) from aque ous solutions containing Arsenazo-I with the organic solvents tridodec ylamine (TDA), 1-[thenoyl-(2)]-3-3-3-trifluoroacetone (HTTA), di(2-eth ylhexyl) phosphoric acid (HDEHP) and tricaprylmethylammonium chloride (TCMA) in xylene has been investigated. Effect of hydrogen ion concent ration in the aqueous phase, Arsenazo-I concentration, as well as the effect of solvent concentration on the extraction was studied. Some al ternatives for separation of the elements studied were recommended ena bling the spectrophotometric determination of these elements using Ars enazo-I without interference.
