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 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.
