ISO/TC6 /N2406 Kraft Liquor – Hydrogen sulphide ion concentration

Scope

This Standard describes a procedure for the determination of sulphide, i.e. the hydrogen sulphide ion concentration, in white, oxidized white and green liquors as well as in black liquor having a dry matter content up to 40 %. The determination also includes the sulphide part of any polysulphide present in the solution.

Note 1 to entry − If the dry matter content of the sample exceeds 40 %, the sample needs to be diluted with oxygen-free water (5.1) to a dry matter content around 20 %. The procedure can result in low results due to unintentional oxidation during the dilution.

Note 2 to entry − The Standard has not yet been tested for oxidized black liquors.
