摘要:

利用金汞齐富集-便携式测汞仪对环境空气中的气态汞进行直接测定，通过对实验条件的筛选及优化，得到最佳条件。经测试，汞的质量在0~9.20 ng之间，与对应的强度呈良好的线性关系，标准曲线的相关系数R²=0.997 1，RSD=87%和9.9%，方法检出限为1 ng/m³。该方法具有简便、快捷、不使用化学试剂等优点，且对环境温度和湿度有一定的抗干扰性，适用于对环境空气气态汞的现场测定。

Abstract:

The gaseous mercury in ambient air was determined directly using gold mercury amalgam enrichment coupled with portable mercury analyzer, and optimum conditions were obtained by screening and optimizing test conditions. Good linearity was obtained when the mercury mass ranged from 0~9.20 ng. The square correlation coefficient of the calibration curve was R²=0.997 1, also, the method showed satisfied precision with the RSD=8.7% and 9.9%. The detection limit of the method is 1 ng/m³.This technique has the advantages of simple, quick, chemical reagents free and anti interference with the environmental temperature and humidity, so it is suitable for field determination of the gaseous mercury in ambient air.
