The equilibria for the extraction system Zr4+/HClO4-NaClO4 (u=4) /HDBP-CCl4 (10-5 to 10-1M) have been studied.In the range of concentrations studied,it has been found that Zr is extracted into the organic phase with the formation of both Zr(DBP)4 and Zr(DBP)4-(HDBP),while in the aqueous phase containing 1 to 4M HC104, Zr exists as Zr (DBP)2(4-i)+ with i=0, 1, 2, 3, 4.The formation constantion of these species have been determined as follows(25°)
