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.

Nitrate nitrogen in wastewater has serious threat. We adopted 201×7, D201, D301 and D301f four anion exchange resins studied adsorption isotherms on the simulate fertilizer factory wastewater (nitrate nitrogen concentration is 300 mg/L), nitrate nitrogen adsorption equilibrium onto four resins can be achieved basically within 30~50 minutes, all adsorption isotherms were in line with Freundlich model, selected D301f resin treated nitrate nitrogen wastewater more perfectly; Adsorption capacity results indicated : adsorption of nitrate nitrogen onto D301f resin was more perfectly at solution pH=6.0~7.0 and temperature at 293K~303K; Thermodynamics experimental results indicated: adsorption of nitrate nitrogen onto D301f resin ΔH>;0, ΔG<;0 and ΔS>;0, which indicted this course could proceed to forward direction spontaneously, and also was endothermic course.
