摘要
介绍用硝酸溶样石墨炉原子吸收光谱法测定钢中痕量Sb。方法的绝对检出限为0.056ng,线性范围0～0.30μg/ml,操作方便,所得结果令人满意。
A method for determining 0.0000x-0.00x% of antimony in iron and steel by graphite furnace atomic absorption spectrometry (GFAAS)is described after decompositon with nitric acid. In the method, the absolute limit of detection is 0.056ng Sb. The linear range is 0-0.30ugSb/ml. The relative standard deviations are less than 5% ( 0.0005% Sb).This method is simple and its results are precise.
