    Abstract

    Lead-antimony alloys used as grid metal in lead-acid batteris are improved by the additions of small amounts of tin and arsenic. The alloy may contain some impurities like bismuth, copper etc.It is very important to control the amounts of these elements within a concentration range of 0.05-0.3 %.The main problem in the polarographic determination of these elements is the interference from the major element. This is overcome by resorting to simple13; separation steps prior to their estimation by polarography.13; This paper describes the polarographic procedures for the estimation of Sb,Sn,As and Bi in lead alloys.
