Evaluation of N,N,N-Dimethylbutylammonium Methanesulfonate Ionic liquid for electrochemical recovery of lead from lead-acid batteries

Physicochemical and electrochemical properties of N,N,N-dimethylbutylammonium methanesulfonate, [DMBA][MS], ionic liquid (IL) have been determined, the potential application for recovery lead from lead-acid batteries is discussed. To optimise transport IL, dependences were measured conductivity, density viscosity with varying amounts excess acid water as a diluent in electrolyte mixture. Molar conductivities obtained molar concentration conductivity measurements used to quantify ionicities these IL mixtures. The solubility PbII PbCO3 was also shown depend strongly on composition. Preliminary results kinetics reduction showed fast Pb deposition potential-controlled electrodeposition morphologies Pb, which may be advantageous design up-scaled electrowinning processes.
