DESCRIPTION
This standard BS ISO 12830:2019 - TC Tracked Changes. Paper, board, pulps and cellulose nanomaterials. Determination of acid-soluble magnesium, calcium, manganese, iron, copper, sodium and potassium is classified in these ICS categories:
  • 85.040 Pulps
  • 85.060 Paper and board

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.
