【摘要】 介绍一种用于冷原子吸收光谱分析法测汞的新型的汞蒸气发生器，并探讨了将该发生器与测汞仪配合直接测定水中痕量汞的工作条件。采用该发生器比旧式汞反应瓶测汞操作简单、快速、灵敏度高。更多还原

【Abstract】 A new self-signed mercury vapour generator with coldvapour-atomic absorption spectonetry used to determine mercury is reported. And the condition of directly determine the trace mercury in the fish-pond water of our school with this generation system and the mercury meas urer machine is discussed. This system is more simple, rapidand sensitive than the old one. The detection limit is 0. 15ng / ml, therelative stand-ard deviation is 7.5 % - 25.2%, the average recovery of mercury is 90.0% ～ 101 .3%.更多还原
