Oxidation of Methyl Orange Solution with Potassium Peroxydisulfate
Authors
Abstract:
Oxidation of Methyl Orange (MO) solution in potassium peroxydisulfate (KPS) homogeneous reaction system without UV irradiation was investigated. The result shows that decolorization of MO increases as the dosage of K2S2O8 increases. The kinetic results demonstrate that the decolorization reaction is a pseudo first-order reaction when the concentration of MO is below 10 mg/L and Langmuir–Hinshewood kinetic model (L-H) can well described it, the value of Ea is 19.5 kJ/mol. The decolorization efficiency is low when the pH value is low (≤2). Result of CODCr shows MO can be effectively mineralized with KPS direct oxidation. The knowledge on the kinetics of the system and influence of some parameters on the system possesses both practical and theoretical values.

Photocatalytic decolorization of Methyl Orange (MO) solution has been studied using phosphotungstic acid (HPA) as photocatalyst. The decolorization reaction of MO solution is photocatalysis. The paper reveals that the optimal loading of photocatalyst for decolorization of MO solution (10 mg/L) is 0.6 g/L. The results show that the photocatalytic decolorization reaction of MO with HPA in a h...

Methyl orange from water was removed by photocatalytic anodic oxidation method using a titanium dioxide array surface. The coating was prepared by anodising a titanium plate using NH4F as electrolyte followed by heat treatment to render a photocatalytic surface under UV light. SEM imaging showed that the array coating consisted of closely spaced 1 m long, 0.1 m internal diameter tubes perpend...
full textHybrid energy cell for degradation of methyl orange by self-powered electrocatalytic oxidation.
In general, methyl orange (MO) can be degraded by an electrocatalytic oxidation process driven by a power source due to the generation of superoxidative hydroxyl radical on the anode. Here, we report a hybrid energy cell that is used for a self-powered electrocatalytic process for the degradation of MO without using an external power source. The hybrid energy cell can simultaneously or individu...
