摘要：

A method is proposed for the determination of lead by generation of its hydride and detection by quartz-tube AAS using a reagent injection FIA system based on the injection of sodium tetrahydroborate. Lead hydride generation was carried out using a combination of 0.5 M nitric acid, 10% m/v hydrogen peroxide and 10% m/v sodium tetrahydroborate. The characteristic concentration obtained was 3.1 ng mL–1 and the detection limit was 2.6 ng mL–1 for an injected volume of 0.125 mL of tetrahydroborate.
