Abstract:
The paper is involved in the electrolysis method for recovering wasted lead material, generated in the production process of lead-acid batteries. The desulfurization procedure was improved by mean of orthogonal test. The corresponding optimal results were obstained with the PbSO4 in lead waste to NaOH mole ratio of 1:1.5, the temperature of 50℃, the solid to liquid ratio of 4∶1 and desulfurization time of 90min. In addition，the influence of electrolyte temperature, concentration of NaOH, electrode spacing and current density on electrolysis process was investigated. The related optimal parameters were NaOH concentration of 3 mol/L，the electric current density of 200 A/cm2, the electrolysis temperature of 45℃ and the electrode spacing of 3 cm. |
