Study concerning the influence of oxidizing agents on heterogeneous photocatalytic degradation of persistent organic pollutants Autori: Anca Florentina Caliman, , , Ioannis Poulios, Maria GavrilescuData aparitiei: November/December 2007 Revista: Environmental Engineering and Management Journal › Vol. 6 › Nr. 6 ISSN: 1843 - 3707 ![]() Abstract
In this paper, the application of the heterogeneous photocatalysis in degradation of a cationic copper phtalocyanine dye, used as model of persistent organic compound is investigated by assessing the efficiency of the process. The influence of hydrogen peroxide on the photocatalytic process is studied using two types of commercial catalysts, such as TiO2 Degussa (88% anatase, 20% rutile) and TiONa Millennium (100% anatase). Another electron acceptor, FeCl3 is also used for investigation of adsorption and photocatalytic degradation efficiencies of the dye on TiO2 Degussa photocatalyst. The results have shown that Millennium photocatalyst and the iron(III) salt exhibit a negative influence upon the studied process. |
