摘要：

Several compounds of the general formula (NH4)((1-x))HxTiOPO4 . nH(2)O (x=0.45-0.75) were prepared by acid treatment of ammonium titanyl phosphate (NTP) at elevated temperature (80-90 degrees C). The protonic phases of the NTP were characterized by elemental analysis, TGA, FT-IR, MAS P-31 NMR and X-ray diffraction. Their ion exchange behavior towards alkali, alkaline earth and some transition metal ions in pure single ion solutions and mixtures was studied. A high capacity and selectivity for potassium and lead makes it promising for certain types of waste treatment and selected analytical separations.
