标准摘要
[中文适用范围]： 本文件规定了在灰化过程中使用Eschka混合物、用酸提取灰分残留物以及氢化物发生原子吸收光谱法或氢化物发生原子荧光光谱法测定固体矿物燃料中砷和硒的方法。该方法也适用于通过氢化物发生电感耦合等离子体原子发射光谱法测定分析物。 [外文原描述]： This document specifies a method using Eschka's mixture during ashing, extraction of the ash residue with acid, and hydride generation atomic absorption spectrometry or hydride generation atomic fluorescence spectrometry, for the determination of arsenic and selenium in solid mineral fuels. The method is also applicable for the determination of the analytes by hydride generation inductively coupled plasma atomic emission spectrometry.
