摘要
研究了金属离子负载树脂对水中氨氮的吸附特征.金属离子负载树脂对氨氮的吸附等温线表明,温度的升高有利于吸附,且吸附等温线都符合Langmuir模型.两种金属离子负载树脂对氨氮的吸附都符合准二级动力学方程.
Adsorption properties of ammonia nitrogen in water onto metal ion-loaded resins were described. The adsorption isotherms of ammonia nitrogen over metal ion-loaded resins were measured. Increasing adsorption temperature enhanced the adsorption of metal ion-loaded resins. Metal ion-loaded resins adsorption behaviors could be well described using the Langmuir adsorption model. The kinetics of metal ion-loaded resins adsorption onto the metal ion-loaded resins could be well described by second order kinetics.
