Two schools of thought have dominated the reduction procedure in cold-vapor atomic absorption: acidic reduction following the method of Hatch and Ott (4), and alkaline reduction as devised by Magos and Cernik (5). Our study investigates the effect of cysteine added to both mercury stock solutions and reducing solutions in combination with acidic and alkaline reduction procedures. The results allow the separate identification of mercury in the sulfhydryl complexed and uncomplexed form.
在冷蒸气原子吸收的还原过程中，有两种思想流派占据主导地位：遵循哈奇和奥特方法（4）的酸性还原，以及马戈斯和切尔尼克设计的碱性还原（5）。我们的研究调查了在汞储备溶液和还原溶液中添加半胱氨酸，并结合酸性和碱性还原程序的效果。结果使得能够分别鉴定巯基络合和未络合形式的汞。
