The electrooxidation of aqueous solutions containing 5mM of o-, m- and p-cresol at pH 4.0 has been investigated using a flow filter-press reactor with a boron-doped diamond (BDD) under galvanostatic electrolysis. All cresols are degraded at similar rate up to attaining overall mineralization. Comparable treatment of the m-cresol effluent on PbO(2) leads to partial electrochemical incineration. ...

This study was performed to find the best experimental conditions for the electrochemical removal of the insecticide dimethoate (C5H12NO3PS2) from aqueous solutions using a lead dioxide niobium anode. The process was studied under galvanostatic polarisation mode. The influence of applied current density (10–50 mA·cm–2), initial chemical oxygen demand COD0 (100–550 mg·l –1), temperature (30–70°C...

This study investigated the degradation of organic pollutants using an advanced electrochemical oxidation technique in a batch reactor cell consisting graphite anode, modified by electrodeposition PbO2, and graphene-modified carbon fiber cathode. The experiment was designed Taguchi design approach with orthogonal array L18 to optimize Chemical Oxygen Demand (COD) electro-Fenton process. Four pr...

In this study, the lead oxide has been successfully synthesized using oxidizing agents (NH4)2S2O8 and applied to decolorize Remazole Black B (RBB) solution. Lead was by batch method through mechanism of reduction-oxidation characterized SEM-EDX XRD. Decolorizing RBB solution performed a modified Fenton method. This study aims determine optimum performance decolorization from oxide. The results ...
