Scope

This document describes a method for determining the content of water-soluble anions in graphene powders using an ion chromatograph. This document is applicable to the determination of water-soluble fluoride ions (F-), chloride ions (Cl-), nitrite ions (NO2-), bromide ions (Br-), nitrate ions (NO3-), sulfate ions (SO42-), and phosphate ions (PO43) in graphene powders. The determination of the content of other water-soluble anions can also be carried out with reference to this document.
