| Abstract: | Using matrix separation and element preconcentration by coprecipitation with Bi(NO 3) 3, a method for FAAS determination of lead in salt was established. This method is simple and rapid. The relative standard deviation was 1.5%～6.6% and the recovery was 97.3%～101.1%. The results ware consistent with those by arbitral method. |
