摘要
本法采用氯酸钾-王水分解样品,直接用空气-乙炔火陷原子吸收法测定岩矿中常量砷。具有操作简便,快速,准确度和精密度较好等优点。变动系数为0.60%～2.00%,测定试样含量为0.0×%～××%的砷。
After decomposition with potassium chlorate and aqua regia, the arsenic content of the sample is immediately detected in rock-foriming minerals with air-acetylene flame atomic absorption spectrometric method. By this approach a simple and effective method is proposed providing better precision and accuracy. The coefficient of variation for As is 0.06%—2.00%. Measuring limits of As range from 0.0×—××.00%.
