GB/T 7731的本部分是对GB/T 7731.8-1987《钨铁化学分析方法　罗丹明Ｂ光度法测定锑量》的修订，包括了罗丹明Ｂ光度法和电感耦合等离子体原子发射光谱法两个分析方法。
本部分代替GB/T 7731.8-1987。
GB/T 7731的本部分规定了用罗丹明Ｂ光度法和电感耦合等离子体原子发射光谱法测定钨铁中的锑量。
本部分适用于钨铁中锑含量的测定。
本部分与GB/T 7731.8-1987比较，主要变化如下：
———对罗丹明Ｂ光度法的标准文本编写格式进行了规范；
———增加了电感耦合等离子体原子发射光谱法。

Scope

Warning: Personnel using this part of GB/T 7731 should have practical experience in formal laboratory work. This section does not address all possible security issues. It is the user's responsibility to take appropriate safety and health measures and ensure compliance with the conditions stipulated in the relevant national laws and regulations. This part of GB/T 7731 specifies the determination of antimony in ferrotungsten by rhodamine B photometry and inductively coupled plasma atomic emission spectrometry. This section applies to the determination of antimony content in ferrotungsten. Measuring range (mass fraction) of rhodamine B photometry: 0.010% to 0.60%; Measuring range (mass fraction) of inductively coupled plasma atomic emission spectrometry: 0.010% to 0.15%.
