| Abstract: | The determination of total molybdenum in soil by sealing digestion graphite furnace atomic absorption spectrometry was studied to establish a method for determination of total molybdenum in soil by sealing digestion graphite furnace atomic absorption spectrometry. Under the proposed conditions, the detection limit of molybdenum was 0.32 μg/L, the RSD between 1.1%. The sample recoveries were in the range of 92.7% - 102.0%. The method is rapid, convenient, accurate, sensitive and suitable for determination of molybdenum in soil. |
