Optimization of process of preparing graphite electrodes with a layer of lead dioxide
 Doros, Stanislav ; Vomáčková, Alena (referee) ; Pilátová, Ivana (advisor)
My study is focused on describing of complex electrochemical methods of preparing of graphite substrate lead dioxide anodes. The theoretical part is devoted to characterization of different parameters which influence the quality (morphology and composition) of the coating. In the experimental part are described the procedures of preparing of the graphite anodes with the lead dioxide coating. In the results are specified the best parameters for which permits the anode to resist high current densities. The whole process consists of substrate treatment, adjustment of current density, period of electroplating and the optimal thickness of plating, control of pH and temperature of solution, additives, rotation of electrode. The lifetime was tested by electrolysis of a potassium chloride water solution for 5 hours by applying 18 A/dm2, the mass of electrode after drying remained constant.
