本文研究了Ｐｂ２＋、Ｆｅ（Ⅲ）与Ｈ＋在氯盐溶液中在石墨阴极与铅阴极上的还原。在石墨阴极上，Ｈ＋、Ｆｅ（Ⅲ）与Ｐｂ２＋共同还原是难以避免的，而在铅阴极上则可避免Ｈ＋的同时还原，可获得更高的铅沉积的电流效率。
In this paper, the reduction of Pb2 +, Fe (Ⅲ) and H + on graphite cathode and lead cathode in a chloride salt solution was studied. On the graphite cathode, the common reduction of H +, Fe (Ⅲ) and Pb2 + is unavoidable, while simultaneous reduction of H + can be avoided on the lead cathode, which leads to higher current efficiency of lead deposition.
