《GB/T 3654.2-2008铌铁 铜含量的测定 新亚铜灵 三氯甲烷萃取光度法》由TC318(全国生铁及铁合金标准化技术委员会)归口,TC318SC1(全国生铁及铁合金标准化技术委员会化学分析分会)执行,主管部门为中国钢铁工业协会。
本部分代替GB/T3654.2―1983《铌铁化学分析方法 新亚铜灵�踩�氯甲烷萃取光度法测定铜量》。本部分规定了用新亚铜灵�踩�氯甲烷萃取光度法测定铌铁中铜的含量。
本部分适用于铌铁中铜含量的测定。测定范围(质量分数):0.0040%~0.18%。 本部分与GB/T3654.2―1983相比较主要进行了以下修改:
―――试料量由0.50g调整为根据含量不同分别为0.50g和1.00g;
―――试液分取量由10mL 调整为根据含量不同分别为25mL、10mL 和5mL;
―――增加标准溶液1mL 含5.00μg铜。
Scope
WARNING: Personnel applying this standard 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 specifies the determination of copper content in ferroniobium by neocuproine-chloroform extraction spectrophotometry. This section applies to the determination of copper content in ferroniobium. Measuring range (mass fraction): 0.0040% to 0.18%.
