【摘要】 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。更多还原

【Abstract】 The reduction of Pb2+, Fe3+ and H+ on graphite or lead cathodes in gold concentrate slurry electrolysis has been studied. The coreduction of H+, Fe3+ and Pb2+ on graphite cathode is unavoidable, but the coreduction of H+ on lead cathode is avoidable, so higher current efficient of lead deposition can be obtained by using lead cathode.更多还原
