SORPTION OF ZIRCONIUM OUT OF SULFATE SOLUTIONS OF POLYAMPHOLYTES

摘要

Computational and experimental data on sorption of zirconium Ions out of sulfate solutions of aminocarboxyl and aminophosphorie add ampholytes are considered and discussed. Based ob the computational data it is shown that zirconium present In sulfate solutions forms a whole series of complex ions (sulfate, hydroxo-, and mixed hydroxosulfate ions). The equilibrium of zirconium ions in sorption of the ions out of sulfate solutions is studied. The behavior of zirconium ions in the course of sorption out of solutions of sulfuric acid over a broad range of concentrations of the ions is explained from the standpoint of the ion state of the metal in the solution as well as the structure and functional features of the ionites. Conclusions concerning the diemism of the process of sorption are confirmed by data of infrared spectroscopic analyses.
