标准摘要
[中文适用范围]: 该方法的原理是将供试品溶解在盐酸和硝酸中,然后用高氯酸蒸发直至出现白烟,将溶液喷入空气-乙炔火焰中,光谱测定279.5 nm谱线的原子吸收由锰空心阴极灯发射。 该方法适用于锰含量在 0.002% (m/m) 和 2.0% (m/m) 之间的情况。 [外文原描述]: The principle of the method specified is dissolving a test portion in hydrochloric and nitric acids followed by evaporation with perchloric acid until white fumes appear, spraying the solution into an air-acetylene flame, spectrometrically measuring the atomic absorption of the 279,5 nm spectral line emitted by a manganese hollow cathode lamp. The method is applicable to manganese contents between 0,002 % (m/m) and 2,0 % (m/m).
