GB/T5121《铜及铜合金化学分析方法》共有27部分。本部分为第24部分。本部分代替GB/T13293.1—1991《高纯铜化学分析方法 催化示波极谱法测定硒、碲》。本方法规定了铜及铜合金中硒、碲含量的测定方法。本方法适用于铜及铜合金中硒、碲含量的测定。测定范围:0.00005%~0.00030%。 本部分与GB/T13293.1—1991相比,有如下变动:
———方法一是对GB/T13293.1—1991的修订,采用氢化物发生原子荧光光谱法代替原标准催化示波极谱法,补充了质量保证和控制条款,增加了精密度条款;
———增加了方法二:火焰原子吸收光谱法,测定范围为0.10%~1.00%(GB/T13293.1—1991中碲的测定范围为:0.00005%~0.0003%,而GB/T5121—1996中没有碲的测定方法,我国现行铜合金中碲的质量分数水平为:0.40%~0.70%)。
