摘要：

Mercury and selenium in the rats' thighbone were determinated by cold atom absorbance and flow injection hydride atom absorbance after digesting by microwave. The method of sample's making and digesting was discussed. The factors of determination of selenium were studied. The detection limits of mercury and selenium are 1.65 and 1.78 ng(.)mL(-1) respectively. The RSD% of mercury and selenium are 4.1% and 3.6% respectively. The linearity of calibration curve of mercury and selenium are in the concentrations of 0-120 ng(.)mL(-1) and 0-50 ng(.)mL(-1) respectively. The recovery of mercury and selenium are 93.72%-101.8% and 95.53%-102.2% respectively.
