Lead in human hair was determined using flame atomic absorption spectrometry and nebulization assisted with hydride generation and K3Fe(CN)6-HCl system. The method is simple and rapid for operation. The performance of the method was compared with conventional flame atomic absorption spectrometry for direct determination of lead. An improved sensitivity by 13.4 fold was obtained compared to the conventional FAAS for direct determination of lead. The effects of several experimental parameters on the lead determination were optimized, and the influences of interference ions on the determination were investigated. The limit of detection (3sigma) of the proposed method was 2.8 microg x L(-1). The method has been applied to the determination of human hair sample satisfactorily with a recovery of 96%-99%.
