Abstract: The peristaltic pump injection hydride generation atomic fluorescence determination method for mercury in drinking water, while the study of acidity, potassium borohydride concentration, lamp current, carrier gas flow rate and other effects on the determination of mercury. Sample recoveries between 97% - 103% The method is simple, fast, high sensitivity. Keywords: peristaltic injection; hydride; atomic fluorescence; mercury 汞是一种剧毒的重金属,具有较强的挥发性。它对生物的毒性既取决于浓度,也与化学形态及生物本身的特征密切有关。汞及其化合物毒性都很大,其有机化合物的毒性尤甚。鱼在含汞量0.010.02毫克/升的水中生活就会中毒;人若食用0.1克汞就会中毒致死。
