Adsorption Characteristics of Natural Zeolite on Ammonia Nitrogen

Abstract:

The experiments of ammonia nitrogen adsorption isotherm and adsorption kinetics were conducted with natural zeolite, particle size of 1～1.5 mm and 2～4 mm separately. The results show that adsorption isotherm of zeolite on ammonia nitrogen accorded with Freundlich type. The maximum adsorption of crude zeolite and fine zeolite on ammonia nitrogen are 5.83 (mg /g) and 18.38 (mg /g) respectively, which indicated that absorption effect of fine zeolite is better than crude zeolite. The adsorption process of crude zeolite on ammonia nitrogen is first-order reaction with rate constant of 0.02( g•m－2•h－1).
