This document describes a method for the determination of carbohydrate composition in kraft lignin, soda lignin and biorefinery lignin. The method is applicable to lignin isolated from a kraft pulping process, a soda pulping process, or lignin obtained by hydrolysis of biomass.
Abstract
Overview
ISO 24215:2022 specifies a standardized laboratory method for determining the isolated from kraft pulping, soda pulping or biomass hydrolysis (biorefinery lignin). The method quantifies the five principal neutral monosaccharides - - to assess carbohydrate content and lignin purity. The procedure uses a two‑step sulfuric acid hydrolysis to release sugars, followed by separation and quantification by either or .
