摘要
用盐酸、硝酸、硫酸分解试样,在盐酸(1+9)介质中,用原子吸收光谱法测定铜精矿中的银,分析范围:10~1 500 g/t,方法的准确度、精密度较好,能满足生产分析的需要.
It is introduced how to determinate silver in concentrate using atomic absorption spectrometry in hydrochloric acid(1+9) medium after decomposing test sample by hydrochloric acid,nitric acid and sulfuric acid.The silver content is ranged between 10 g/t and 1 500 g/t.This method is with high precision and accurateness and can meet the demands of production analysis.
