Heterogenous Fenton-Like Oxidation of Reactive Black 5 in Water Using Pyrite Cinder

Abstract:

As the Fenton-like oxidation reaction based on iron-bearing minerals could solve some problems of the traditional Fenton oxidation reaction, it became a talking point in academic circles worldwide recently. For the Fenton-like reaction, catalyst selection is an important research parameter. The new Fenton-like reaction uses iron-bearing cinder as catalyst by employing Reactive Black 5 (RB5), the object of investigation, as the target pollutant. By examining the dosage of catalyst, hydrogen peroxide, initial pH, reaction time, concentration of pollutants, optimized reaction conditions can be obtained. Results show that pyrite cinder gives rise to high catalytic activity in the Fenton-like reaction. When 5ml/L of hydrogen peroxide and 10g/L of cinder were added to 75mg/L of dye, the removal rate of RB5 was found to be 96% in 4 hours. Compared to the traditional Fenton reaction, it has a wider pH range and higher catalytic oxidation activity, especially under alkaline condition.
