| Abstract: | Graphite furnace atomic absorption spectrometry was employed to determinate the lead in complex composition of water treatment agent polyaluminum ferric chloride. Through adding matrix modifier ammonium diacid phosphate to reduce interference , the traced lead in samples was determined for practical application. The results were consistent with the determination results by standard method , and the standard recovery rate was between 80% and 120% which was satisfactory. |
