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.
The photocatalytic decomposition of Reactive Bright Orange (KGN) with polyoxometale, phosphotungstic acid (PTA) and titanium dioxide (TiO2), was investigated in an aqueous solution with a 253.7nm, 20W UV lamp. The photocatalytic degradation organic product of KGN was analyzed with HPLC. Photocatalytic degradation anion product of KGN was analyzed with UV-VIS spectrophotometer. The results revealed that the photocatalytic degradation organic product of KGN with PTA and TiO2 in a homogenous aqueous solution was different after 2 hours of irradiation. But for anion product of KGN was nearly same with the above two different catalysts, NH4+, NO3- and Cl- were detected soon after the photocatalytic reaction, except SO42- which was not detected in PTA reaction system, while it was detected in the TiO2 reaction system after 10 hours of irradiation. The photocatalytic degradation mechanism of KGN with PTA and TiO2 maybe different.
