由于火法铅回收的能源成本不断增加、所产生的二氧化碳排放以及铅排放到空气中的铅暴露对健康的灾难性影响，越来越需要开发从报废铅酸电池中回收铅的新工艺。为了解决这些问题，我们正在开发一种离子冶金工艺，旨在取代几千年来主导铅生产的火法冶金工艺。提出的工艺包括将铅盐溶解到深度共晶溶剂（DES） Ethaline 200中，这是一种由氯化胆碱和乙二醇以1:2摩尔比混合在一起形成的液体。一旦溶解，铅可以通过电沉积回收，然后可以回收液体进行进一步的铅回收。首先，利用DESs溶解所涉及的铅化合物（PbCO3、PbO、PbO2和PbSO4），并利用电感耦合等离子体发射光谱法（ICP-OES）测量其溶解度。得到的Pb2+物质被还原并作为元素铅在电化学电池的阴极上电沉积；循环伏安法和计时安培法被用来测定电沉积的行为和机理。采用扫描电镜（SEM）和x射线光电子能谱（XPS）对电沉积膜进行了表征。我们将讨论这些过程的影响和机会。
There is a growing need to develop novel processes to recover lead from end-of-life lead-acid batteries, due to increasing energy costs of pyrometallurgical lead recovery, the resulting CO2 emissions and the catastrophic health implications of lead exposure from lead-to-air emissions. To address these issues, we are developing an iono-metallurgical process, aiming to displace the pyrometallurgical process that has dominated lead production for millennia. The proposed process involves the dissolution of Pb salts into the deep eutectic solvent (DES) Ethaline 200, a liquid formed when a 1 : 2 molar ratio of choline chloride and ethylene glycol are mixed together. Once dissolved, the Pb can be recovered through electrodeposition and the liquid can then be recycled for further Pb recycling. Firstly, DESs are being used to dissolve the lead compounds (PbCO3, PbO, PbO2 and PbSO4) involved and their solubilities measured by inductively coupled plasma optical emission spectrometry (ICP-OES). The resulting Pb2+ species are then reduced and electrodeposited as elemental lead at the cathode of an electrochemical cell; cyclic voltammetry and chronoamperometry are being used to determine the electrodeposition behaviour and mechanism. The electrodeposited films were characterized by scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS). We discuss the implications and opportunities of such processes.
