锗,当今被称之为是一种重要的抗癌元素、含锗药物在临床中显出抗癌活性,对癌细胞起一定的抑制作用。因此对于各种药物和营养口服液,滋补品中这种具有一定疗效的锗元素的含量分析有一定的意义。近几年有关石墨炉原子吸收法测定常量至痕量级锗时有报导,由于锗是属于低温易挥发元素,在石墨炉原子吸收法测定锗的过程中,锗与未原子化的气态 GeO 易挥发而损失。因此锗的测定灵敏度和重现性难以提高。文献采用 CCl_4萃取和水反萃取分离试样中的共存离子和有机组分,并采用涂钨石墨管以减少锗的挥发损失,文献采取萃取的手段和塞曼效应扣除背景测定了人参中的锗,本文研究了一种只用氘灯扣除背景,基体改进剂结
Alas, nowadays it is known as an important anticancer element and anticonvulsant drug that shows anticancer activity in the clinic and has a certain inhibitory effect on cancer cells. Therefore, for various drugs and nutritional oral liquids, the analysis of the content of the germanium element with certain curative effect in the nourishing products has certain significance. In recent years, graphite furnace atomic absorption spectrometry has been reported for the determination of trace amounts of ruthenium, and since ruthenium is a low-temperature volatile element, the presence of ruthenium and unatomized gaseous GeO in the process of determination of ruthenium by graphite furnace atomic absorption spectrometry is reported. Loss of volatilization. Therefore, it is difficult to improve the measurement sensitivity and reproducibility of hydrazine. The literature uses CCl_4 extraction and water back extraction to separate the coexistent ions and organic components from the sample, and uses a tungsten-coated graphite tube to reduce the volatilization loss of the crucible. The literature adopts the extraction method and the Zeeman effect subtracting background to determine the enthalpy in ginseng. This paper studies a depletion background using only Xenon lamps, matrix modifiers
