石墨炉原子吸收测定铍,由于基体的影响,常常采用标准加入法,预先分离基体和在标准溶液中加入基体元素等方法,这些方法比较费时,给分析带来许多不便。近年来,由于等温平台石墨炉和加基体改进剂等方法,对消除基体元素的干扰比较成功,因此被人们普遍采用。本工作不用平台,不加基体改进剂,而采用最大功率加热方式,分别利用热解镀层石墨管(简称PGT),普通石墨管(简称GGT)和衬钽管(简称TaT),直接分析岩石样品中 Graphite furnace atomic absorption spectrometry beryllium, due to the influence of the matrix, often using standard addition method, the separation of the matrix in advance and the addition of matrix elements in standard solutions and other methods, these methods are time-consuming, to the analysis of a lot of inconvenience. In recent years, as a result of isothermal platform graphite furnace and matrix improvement agent and other methods, to eliminate the interference of matrix elements more successful, so it is widely used. This work does not require a platform, without matrix modifier, and the maximum power heating method, direct use of pyrolytic coating graphite tube (PGT), ordinary graphite tube (referred to as GGT) and lined with tantalum tube (referred to as TaT), direct analysis of rock samples in
