%X An integrating equation of moving boundary model was used to describe the kinetics with changing bulk concentration of removing Mg2+ from demagging waste solution of phosphate ore by 0017 resins. The general kinetical equation was obtained. The ion exchange process of Mg2+ is controlled by ion diffusion through particles. The apparent activation energy is calculated to be 24.11 kJ/mol, and the apparent reaction order of Mg2+ is 1.0.
