Abstract
Lead removal from a simulated wastewater was achieved using a spiral-wound woven wire mesh rotating cylinder electrode. The operating parameters for the cathodic deposition of lead were optimised by Taguchi approach. Three operating parameters were considered as control variables. These are: initial lead concentration (25–125 ppm), rotation speed (200–1,000 rpm) and current (0.1–0.5 A). Removal efficiency was considered as a response for the optimisation process. The results indicate that the current has the most significant influence on the removal efficiency than the other parameters. The optimum operating parameters were a current of 0.5 A, rotation speed of 600 rpm and Pb(II) initial concentration of 100 ppm, in which the initial lead concentration was deceased from 100 ppm to less than 5ppm resulting in a removal efficiency of 95.65% within 30 min of electrolysis while a complete removal was achieved at 50 min. Taguchi methodology was proved to be successful for optimising lead removal process.
