本文采用碘 -活性碳吸附管收集天然气管道中的汞 ,然后用微波消解法溶样 ,再用冷原子吸收光谱法及原子荧光光谱法分析测定汞 RSD <5 % ,方法具有简便 ,快速 ,避免汞挥发损失的特点 ,用于实际测定 ,得到满意结果 In this paper, mercury in natural gas pipeline was collected by iodine-activated carbon adsorption tube, and then dissolved by microwave digestion method. The RSD of mercury was determined by cold atomic absorption spectrometry and atomic fluorescence spectrometry. The method was simple, rapid, and avoidable Mercury volatilization loss characteristics, for the actual determination, get satisfactory results
