Scope

Scope: This document specifies the reagents, instruments and equipment, experimental procedures, precision, and test reports for determining the content of potassium, sodium, calcium, magnesium, iron, and silicon in polyacrylonitrile-based carbon fiber samples using inductively coupled plasma atomic emission spectrometry. This document is applicable to the determination of the content of potassium, sodium, calcium, magnesium, iron, and silicon in raw filament, pre-oxide filament, and carbon filament made from acrylonitrile. The range of multi-element content determination is shown in Table 1. The determination of other trace elements in polyacrylonitrile-based carbon fiber can be used for reference.
