ISO 11723:2016 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.
Abstract
Overview
ISO 11723:2016 is an international standard that specifies a precise analytical method for determining and content in solid mineral fuels. This method combines the use of Eschka’s mixture during ashing with an acid extraction step, followed by quantification through hydride generation atomic absorption spectrometry (AAS) or atomic fluorescence spectrometry (AFS). The standard is essential for ensuring accurate, reproducible measurements of these toxic elements in coal, coke, lignite, and other solid mineral fuels, supporting compliance with environmental and safety regulations.
