Processing of Sludge from Spent Lead-Acid Batteries by Electrochemical Method
Abstract: The process of electrochemical dissolution of lead sludge in hydrogen borofluoride electrolyte was studied, namely, preliminary preparation of the objects of study – activation of active lead mass was carried out, and the dissolution rates of battery plates (anode), the dissolution rate of lead sludge (anode), the rate of lead release at the cathode, cathode current density and current output were determined. It is shown that the process of converting lead compounds (lead dioxide and lead sulfate) into an acid-soluble form at pH 9–10 leads to a decrease in the concentration of lead in the washing waters in comparison with the neutral medium by tens of times. When using sludge in an electrolytic basket as an anode, as a more common form of lead waste, the dissolution rate increases by 17…20 % compared to the battery plate, which significantly speeds up the process of electrochemical processing of SKA in the form of sludge.
Keywords: lead sludge, used car batteries, hydrogen borofluoride electrolyte, lead.
