摘要
用动边界模型积分方程描述了0017树脂脱除磷矿脱镁废水中的Mg2+的有限浴交换动力学,得到了动力学总方程. Mg2+的交换过程属颗粒扩散控制,表观活化能为24.11 kJ/mol,[Mg2+]的表观反应级数为1.0.
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.
