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.
Humic acid (HA) photodegradation and impact factor by Ag deposited TiO2/UV system which prepared by using photodeoxidation method were investigated in this paper. The SEM and EDS results determined the Ag deposition on TiO2 surface. A suitable Ag loading and roasting temperature could improve photocatalytic activity of TiO2 and the optimum conditions were 0.8wt% and 400°C respectively. The removal of HA increased as adding TiO2 dosage and decreased with rise of its initial concentration. Pseudo first-order kinetics with regard to HA concentration can be used to describe the photodegradation.
