标准范围

规定方法的原理是将试验部分溶解在盐酸和硝酸中，并将溶液稀释至已知体积，将已知体积的溶液引入原子吸收光谱仪的电热雾化器，测量锑灯发出的217,6 nm光谱共振线能量的原子吸收。该方法适用于锑含量在00005%（m/m）和0010%（m/m）之间的情况。

The principle of the method specified is dissolving a test portion in hydrochloric and nitric acids and dilution of the solution to a known volume, introducing a known volume of the solution into an electrothermal atomizer of an atomic absorption spectrometer, measuring the atomic absorption of the 217,6 nm spectral resonance line energy emitted by an antimony lamp. The method is applicable to antimony contents between 0,0005 % (m/m) and 0,010 % (m/m).
