Color and COD Removals of Chemistry Laboratory Wastewater by Fenton’s Reaction

Abstract

The aims of this research were to study the color and COD removals of chemistry laboratory wastewater by Fenton’s reaction using batch test. The effect of optimum conditions color and COD removals of chemistry laboratory wastewater by Fenton’s reaction were investigated such as pH, H₂O₂:Fe²⁺ mole ratio and reaction time. The results showed the optimum conditions of the color and COD removals for chemistry laboratory wastewater by Fenton reaction were initial pH 2, H₂O₂:Fe²⁺ ratio in 15:1 (mole/volume) and shaking with 150 rpm at room temperature. The optimum condition, the highest color removal of chemistry laboratory wastewater was 92.15.0.00% at reaction time for 60 minutes. Meanwhile, the highest COD removal of chemistry laboratory wastewater was 63.90.0.26% at reaction time for 30 minutes.
