Removal of ammonium ion from water by Na-rich birnessite: Performance and mechanisms
Y Cheng, T Huang, X Shi, G Wen, Y Sun - Journal of Environmental …, 2017 - Elsevier
Na-rich birnessite (NRB) was synthesized by a simple synthesis method and used as a high-
efficiency adsorbent for the removal of ammonium ion (NH 4+) from aqueous solution. In
order to demonstrate the adsorption performance of the synthesized material, the effects of
contact time, pH, initial ammonium ion concentration, and temperature were investigated.
Adsorption kinetics showed that the adsorption behavior followed the pseudo second-order
kinetic model. The equilibrium adsorption data were fitted to Langmuir and Freundlich …
