The uptake of cyclohexylamine with α-zirconium phosphate was studied by means of the pH-titration method. Cyclohexylamine was loaded up to 75% of the ion-exchange capacity of α-zirconium phosphate. Chemical analysis, thermal analysis, infrared spectroscopy, and X-ray diffractometry were used to characterize the product obtained at the final step of pH titration, which was referred to as the cyclohexylammonium form. The chemical composition can be presented as Zr(C<SUB>6</SUB>H<SUB>11</SUB>NH<SUB>3</SUB>)<SUB>1.5</SUB>(H)<SUB>0.5</SUB>(PO<SUB>4</SUB>)<SUB>2</SUB>·H<SUB>2</SUB>O. The interlayer distance of the exchanger expanded to 18.4 Å upon the uptake of cyclohexylamine. The cyclohexylammonium ion was exchanged easily with the nickel(II) ion in a solution.
