Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
To further understand the nitrogen removal mechanism in leachate treatment using aged-refuse-based bioreactor, 10 year aged refuse was used as adsorbent, ammonium chloride as adsorbate. The adsorption isotherms and thermodynamics, and adsorption mechanism were studied. The results show that: (1) The isothermal adsorption process of NH4+ on aged refuse can be fitted by Freundlich equations with a high correlation coefficient (0.9873 ~ 0.9907). (2) The adsorption process of NH4+ on aged refuse is spontaneous and exothermic. Temperature is conducive to the spontaneous adsorption but adsorption decreased. (3) In the absorption of ammonium by aged refuse, the main force is the hydrogen bonding and dipole bond for physical adsorption.
