Abstract
This work assesses the electrocatalytic (EC), photocatalytic (PC), and photoelectron-catalytic degradation (PEC) of Amaranth azo dye with ammonium persulfate (APS). The results were observed that the photoelectrocatalytic degradation technique more efficient than other techniques. The effects of operational parameters such as initial pH and APS concentrations on color removal efficiency were investigated. Decolorization and degradation were found to depend strongly on the system parameters.The dye decolorization was enhanced using pH 2.0. The rate of degradation of Amaranth with APS followed pseudo–first order kinetics in the dye concentration. Decolorization efficiency (%) and degradation rates of amaranth were increase with increasing APS concentration.
