| Abstract: | The method for the determination of strontium in soil by microwave digestion-flame atomic absorption spectrophotometry was developed. The sample was pretreated by microwave oven with the optimized digestion parameters, and heated on electric cooker to drive away acid. The detection limit was 3.0 mg/kg, the recovery was in the range of 84.7%-107% and the relative standard deviation was less than 5%. The method is rapid, simple, and accurate with wide linear range. |
