A new family of ion exchangers having a layered structure and a general composition of Zr(03PC6H4S03H)x(HPO))2. xhas been prepared. The ion exchange behavior of two members of the family (with x - 0.43 and 0.767) towards alkali and alkaline earth cations was determined. The sulfonic acid groups provide strong acid cation exchange sites while the phosphate protons exhibit moderate to weak acidity. Separation factors for the two layered exchangers were much higher than those for a conventional polystyrene sulfonic acid and even for zirconium phosphate. 1989, Taylor & Francis Group, LLC.
