Abstract：The adsorption of ammonia-nitrogen on a macro-reticular weak acid resin (D113) with a strong acid resin (001×7) was analyzed experimentally to identify the thermodynamics and kinetics of the absorption process. The result showed that: 1) increasing resin concentrations increased the ammonia removals of the two resins even though the adsorption rate decreased; 2) a basic solution increased the adsorption capacity of the two resins, and 3) the adsorption capacity of the two resins increased with temperature. The adsorption isotherm of two resin combination was fit with the Langmuir adsorption model with the kinetics close a pseudo-second equation. The process of ammonia adsorption on the resins was a spontaneous, endothermic reaction with increasing entropy.
