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.
At present the rare earth fertilizer were widely used in agricultural production, there were many researches on the biological effects of rare earth fertilizer. But there were few researches to study the effect of rare earth on the migratory characteristic of heavy mental. Experiments were conducted to study the effect of lanthanum on absorption and desorption of copper in soil. The results showed that the adsorption isotherms of copper in the soil could be described by the Langmuir and Freundlich model, and the Freundlich model appeared to fit better to the isotherms. The existence of lanthanum reduced copper adsorption in the soil, with the increase of lanthanum concentration, the copper adsorption in the soil gradually declined, whereas copper desorption was increased slowly when lanthanum concentration rose to 20 mg kg-1. This can intensify and complicate the pollution of copper in the soil.
