ABSTRACT
This document specifies the procedure for the determination of acid-soluble magnesium, calcium, manganese, iron, copper, sodium and potassium by atomic absorption spectrometry (AAS) or by inductively coupled plasma emission spectrometry (ICP/ES). The acid-soluble element comprises the acid-soluble part of the incineration residue, i.e. that part of the ignition residue obtained after incineration which is soluble in hydrochloric acid or nitric acid. In cases where the residue is completely soluble, the result obtained by the procedure specified in this document is a measure of the total amount of each element in the sample.
