title: [Determination of trace mercury in soil by hydride generation atomic fluorescence spectrometry].
abstract: A method for the rapid determination of trace mercury in soil by hydride atomic fluorescence spectrometry is reported in this paper. The sample of soil is leached (at 80 degrees C-100 degrees C) with aqua regia (H2O + aqua regia, 1 + 1). The concentration of KBH4 used in this method is studied. Trace mercury in reference material (polluted farming soil) is determined by the described method too. The result obtained is in good agreement with standard value. The RSD is 1.4% and the recovery of mercury is 87%-105%. This method is proved to be rapid, simple and accurate.
