Abstract: |
A new method was established to detect the arsenic in ambient air by using impregnated filter adsorption, microwave digestion and atomic fluorescence spectrometry, which improved the original sampling method and was more effective than the wet digestion. The method greatly reduced the detection limit to satisfy emission limit requirements in the national standard GB 3095-2012. |
