英文名称：Paper, board, pulps and cellulose nanomaterials — Determination of acid-soluble magnesium, calcium, manganese, iron, copper, sodium and potassium
发布日期：2019-07
标准范围
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.
This document is applicable to all types of paper, board, pulps and cellulose nanomaterials.
The limit of determination depends on the element and on the instrument used.
