چکیده

In this study, decolorization of wastewater samples taken from the paper industry is investigated using electrochemical peroxidation process. The process a part advanced oxidation processes, which based on Fenton’s chemical reaction, provided by addition external H2O2 into reaction cell. iron used as anode and graphite cathode put at fixed distance 30 mm in glass cell was filled with solution containing sodium chloride supporting electrolyte. Factors such pH, current intensity, hydrogen peroxide concentration, time treatment were studied. results illustrate that all these parameters affect efficiencies dye removal oxygen demand (COD) reducing. maximal contaminants achieved under acid (pH 3) condition, applied 1 A, concentration 0.033 M. At conditions, efficiency reached 100 83 % COD after 40 minutes sample treatment. addition, electrical energy consumption for calculated, showing increase intensity increased. obtained suggest can be removing compounds industrial wastewaters high efficiency.

Decolorization of synthetic textile wastewater using electrochemical cell divided by cellulosic separator

BACKGROUND Annually, large quantities of dyes are produced and consumed in different industries. The discharge of highly colored textile effluents to the aquatic environments causes serious health problems in living organisms. This paper investigates the performance of each of the electro-oxidation and electro-reduction pathways in the removal of reactive red 120 (RR120) from synthetic textile ...

The Modified Fenton Process for Decolorization of Dye Wastewater

A novel modified Fenton process using heterogeneous catalyst (swarf) was developed to catalyze the oxidation reaction of azo dye Acid Red 18. It was found that swarf could be used to replace iron salts as a catalyst for the Fenton reaction. The examined continuous Fenton process proved to be very efficient for decolorization of simulated wastewater containing 100 mg/dm3 Acid Red 18. Performance...
