Abstract
The total mercury in soil was determined directly by Thermal decomposition-Cold vapor atomic absorption spectrometric method, which was used by portable mercury analyzer. The uniform samples without drying and digestion could be measured directly. The performance indicators of established method were satisfied in linear range, accuracy and precision. The limit of detection could approach to be as low as 1 μg/kg. Compared to the other methods to measure soil samples, the aforementioned method could achieve the similar results. The analyzer is portable and could measure the mercury in soil easily and quickly without using any reagents.
