Abstract

The study investigates the feasibility of the application of electrolytic treatment in removing lead from the electrolyte of used lead acid batteries. The effect of the operating current on lead removal was investigated from the residual lead content. Also, the effects on pH and temperature were observed. Results showed that the residual lead content has no significant response on varying the experimental operating currents. The maximum percent lead removal of about 84.4461% was achieved at 10 A operating current with 57 mins electrolysis time. On one hand, it was observed that temperature increases with increasing electrolysis time. On the other hand, pH has no significant response on varying electrolysis time. The maximum computed charge dose for the electrolytic recovery of lead was found to be 32,248 C/mg Pb removed. For this charge dose value at 7.5 A, the computed values for energy requirement and total treatment cost were 0.0490 kWh and PhP 645.4908 per m3 wastewater, respectively.
