| Abstract: |
| A microwave digestion-atomic fluorescence spectrometry method was established to fast determining Se in the soil for cyclically and organically planting traditional Chinese medicine. The conditions for sample digestion and instrument operation were optimized. The method has small standard deviation, good repeatability and precision. The average recovery for Se is 102.3%. The method is simple, fast, accurate, reliable and environmentally friendly. The Se contents in the soil , in which the traditional Chinese medicine had been cyclically and organically planted for three years and two years are 0.428 mg/kg and 0.350, respectively. |
