摘要
对石墨炉原子吸收法和钯基体改进剂测定微量镉的实验方法进行了研究,讨论了钯用量对镉测定灵敏度的影响,根据实验结果及X光电子谱分析,提出了钯存在下镉在石墨管内的原子化过程是一个以物理作用为主,同时伴有钯的催化还原作用的复杂的物理-化学过程的观点.
A method for the determination of micro quantity of Pd with Pd modifier and graphite furnace atomic absorption spectrometry have been studied, the relationship between the sensitivity of Cd and the quantity of Pd are discussed. According to the results of experiments and the analysis of X-ray photoelectron spectroscopy, the atomization of Cd was mainly a physical process and Pd still behaves a catalytic effect.
