微波消解－原子荧光法测定环境空气中的砷

摘要

建立了浸渍滤膜吸附－微波消解－原子荧光法测定环境空气中的砷的方法，改进了原有的采样方法，有效地克服了原方法中湿法消解的缺点，并大大降低了检出限，能够满足《环境空气质量标准》（GB 3095－2012）中对砷排放的参考浓度限值要求。%A new method was established to detect the arsenic in ambient air by using impregnated filter adsorption,microwave di-gestion and atomic fluorescence spectrometry,which improved the original sampling method and was more effective than the wet di-gestion.The method greatly reduced the detection limit to satisfy emission limit requirements in the national standard GB 3095-2012.
