Photocatalytic treatment of industrial pulp and paper mill wastewater using Fe2O3/TiO2 nanocomposite

Title : Photocatalytic treatment of industrial pulp and paper mill wastewater using Fe2O3/TiO2 nanocomposite

Abstract:

In this study the pollutants (COD,CODdis, TOC, BOD5, TSS, TDS, color) were degraded by Fe2O3-TiO2 nanocomposite produced under laboratory conditions. The effects of pollutant concentration  (COD dis=  500,  700,  1000, 1500 and 2000 mg/l),photocatalytic power ( 25, 50, 75, 100 and 125 W/m2), photocatalytic time (15 , 25, 35, 45 and 60 min),nanocomposite concentration ( 2, 4, 6 and 8 mg/l), Ph( 5, 7 and 8), presence of some anions (BrO3,  and ClO4)  and  increasing temperatures ( 20, 30 and 40 Oc) during treatment were investigated. The pollutants were removed with yields as high  as 99 %  saccording to Langmuir-Hinshelwood kinetic model, with pollutant rate constants varied between  2  and 3. X 10-2 min-1  in the presence of  4 mg/l Fe2O3-TiO2,  1500 mg/l  COD dis,  50 W/m2 power after 25 min at Ph=5 ant 20 Oc temperature. The magnetic  properties of Fe2O3-TiO2 showed high reusability  ( 99% removal for 50 times)and easy separation of the photocatalyst from the wastewater.
