镍 银、铋、镉、钴、铜、铁、锰、铅和锌含量的测定 火焰原子吸收光谱测定法

[中文适用范围]： 适用于表1规定范围内的精炼镍、锻镍和铸造镍。 该方法适用于所列任何一种或多种元素的独立测定。 如果制备了特殊的标准溶液，铁的下限可以扩展到低于 0.0025 % (m/m)。 通过对方法进行微小修改，可将钴和铜的测定上限提高至 2% (m/m)。 对于潜在的干扰，请参阅第 10 条。 [外文原描述]： Applies to refined, wrought and cast nickel within the ranges specified in table 1. The method is applicable to the independent determination of any one or more of the elements listed. The lower level for iron can be extended to less than 0,0025 % (m/m) provided a special standard solution is prepared. The upper limit for the determination of cobalt and copper can be raised to 2 % (m/m) by a minor modification to the method. For potential interferences, see clause 10.
