| Abstract: | The impurities of Ca, Mg, Si, Mn in negative material of Ni-Cd batteries are converted into sulfate and after drying and grinding then determined by using emission spectrum under 6A of current and 45s of exposure time. Ba is used as internal standard element. With the retrieval tests,this method is proved as accurate,easy,and quick. |
