Excerpt from the Study
The following conclusions were be drawn from the work
1. Undoped goethite catalyst, copper doped (A) catalyst with 0.2 wt% Cu,copper doped (B) catalyst with 1.6wt% Cu and copper doped (C) catalyst with 3.3wt% Cuwere synthesized by precipitation method and characterized using XRD, surface area analysis, AAS and SEM techniques. 2. Batchwise depuration of the Kaduna refinery wastewaterwas achieved at optimum conditions of 360 minutes reaction time, pH of 3, catalyst loading of 55mg/L and hydrogen peroxide dosage of 1.1g/L. 3. Copper doped (C) catalyst yielded the highest depuration percentage of 86% at pH of 3, 84% at pH of 6.5 and 72% at pH of 10, respectively 4. Appreciable depuration percentage was achieved at near neutral pH (pH of 6.5), with 67.44% for the undoped catalyst, and 79%, 82.56% and 83.72% for the Cudoped A, B and C goethite catalysts, respectively. 5. Cu-dopedcatalysts yielded improved depuration percentage, depicting that the doped catalysts have great potential as an efficient tool for Fenton depuration of petroleum refinery wastewater. 6. The stability of the synthesized copper doped catalyst had less catalyst deactivation over the first to third cycle.Sothe catalyst will perform fairly well in practical industrial application. 7. The Depuration process can be used as an efficient, less expensive and environmental friendly technique for petroleum refinery wastewater depuration.
