Nitric acid and hydrofluoric acid and hydrochloric acid system was applied to digest soil in microwave. Arsenic was detected by atomic fluorescence spectrometry after the On -guard II H column was used to removal other heavy metals in the digestion solution.This method is simple to conduct the pre-treatment process and saves time and human resources with fewer doses of acids.The recovery rate was 94.4%to 105.6%that could reach the monitoring requirements.
