ABSTRACT The presence of ammonia in wastewater from industry activities is an important environmental issue; therefore, an adsorption process is one viable alternative process that can be used to reduce concentrations, and accordingly, 10 resins and 6 zeolites were tested for the removal of ammonia from real wastewater (3.8 to 8 mg/L NH3 − N) containing other cations. In subsequent tests, the performance of the most promising adsorbents (four resins & two zeolites) was further characterized using isotherms and kinetic experiments. Adsorbent equilibrium capacities in the range of 0.2 to 0.4 mg/g were determined for ammonia concentrations of approximately 1 mg/L.
