title: [Determination of lead in water depuration agent with single-slotted quartz tube by atom-trapping atomic absorption spectrometry].
abstract: The determination of lead in water depuration agent with single-slotted quartz tube by the fuel-lean flame trapping and pulsed fuel-rich flame discharge atom-trapping atomic absorption spectrometry have been investigated. The optimum conditions for the determination and the tolerance of interfering elements are studied. A simple and rapid method is proposed. The linear relationship holds in the range 0-100 micrograms.L-1, the recovery is between 97%-103% and the relative standard deviation is 2.6%-2.8%. The proposed method has been applied to the determination of lead in water depuration agent samples with satisfactory results.
