This document specifies a method for the determination of total fluorine in coal, coke and fly ash. From measurement of the total fluorine alone, it is not possible to estimate the amount of fluorine released to the environment by utilization of the coal and subsequent disposal of the ash residue.
Abstract
Overview
ISO 11724:2019 specifies a laboratory method for the determination of total fluorine in solid mineral fuels - specifically . The method uses (thermal treatment at about 1 200 °C in an oxygen/water vapour atmosphere) to volatilize fluorine compounds, collects the pyrohydrolysate in an absorption solution and quantifies fluorine by or . The standard also notes a key limitation: .
