Abstract

This study was conducted to examine the adsorption capacity of $NH_{3}-N$ by natural zeolite for the purpose of investigating the possibility for $NH_{3}-N$ eliminator of korea natural zeolite. The dominant clay minerals of zeolite was clinoptiloite. The amount of $NH_{3}-N$ adsorption by zeplite was not significantly affected by the particle size of zeolite and increased with increasing the ratio of zeolite to the volume of solution. Removal ratio of 100% of NH$_{3}$-N by non, 1st, 2nd regenerated cloumn was continued separately during 4.5, 18, 30hr and this amount was each 0.081, 0.324, 0.540g $NH_{3}-N/zero$.100g. The eluenting amount of K, Ca, Mg was increased on the zeolite cloumn according to that of Na decreased. The amount of 74% of $NH_{3}-N$ was desorved on the zeolite cloumn for regenerating treatment during 8hr. The perfect removal amount was $0.216gNH_{3}-N/zero$.100g on the zeolite cloumn with field sample.
