近年来,在环境污染问题上,大家都很关心生活环境中汞的行为,希望对各种环境试样中微量汞的检测寻求一种快速简便的分析方法。我们曾研究了一种原子荧光测汞仪,并对水样中的汞进行了分析,本文对仪器的放大线路及造形和结构方面作了改进。目的是用于土壤、粮食、矿物岩石和鱼肉等试样的分析。试验结果表明,该法用于上述试样中汞的分析效果较好。具有仪器简单,操作方便,快速,准确等优点。测定下限为O.lppb。
In recent years, environmental pollution, everyone is concerned about the behavior of mercury in the living environment, hoping to detect trace mercury in various environmental samples to find a quick and easy analytical method. We have studied a mercury atomic fluorescence spectrometer, and mercury in water samples were analyzed, this article on the amplification circuit and the shape and structure has been improved. The purpose is to analyze soil, grain, rock and fish samples. The test results show that the method used for the above analysis of mercury samples better. With the instrument is simple, easy to operate, fast, accurate and so on. The lower limit of determination is O.lppb.
