Ammonium removal from aqueous solutions by using natural Chinese (Chende) zeolite as adsorbent
TL;DR: Kinetic analysis showed that the adsorption of ammonium on zeolite at different ranges of particle size well followed the pseudo-second-order model and followed the intra-particle diffusion model only during the initial 60 min of the adsorbent process.
