| 摘 要： | Kinetics of chloride/sulfate,chloride/nitrate and nitrate/sulfate forward exchanges and reverse exchanges at solution concentrations of 1N,0.2N and 0.02 N on 201×7 strong base anion exchange resin,respectively,have been examined at 25℃.It is found that the forward and the reverse exchange rates of the two given ions at low solution concentration,respectively,under identical conditions can be controlled by different mechanisms,while those at high solution concentration are all controlled by particle diffusion.The ternary exchange rates of sulfate/(chloride+nitrate) and nitrate/(chloride+sulfate)have also been examined.
