PbCl2 can be separated out via chloridizing volatilization because of the low boiling point and high vapor pressure [28], and thus can be processed by molten salt electrolysis for Pb production. Fig. 1... secondary lead production [1]. On the other hand, spent LABs should be disposed properly from an environmental point of view, due to the high toxicity of lead [5]. Therefore, efficient and sustainable......
