Adsorption and kinetics of resin on ammonia-nitrogen out of rare earth smelting wastewater

This article studies the ammonia-nitrogen treatment in rare earth smelting waste water by ion exchange resin method. Kinetics experiments are performed for deciding the effects of resin amount, time, temperature and pH. The adding of resin amount, temperature, time and pH value are favorable for increasing ion exchange capacity. The ion exchange of D113 resin on ammonia-nitrogen conforms to the two kinetic equation.
