Sammanfattning
Different conventional lignin determination methods have been applied to hemicellulose-rich extracts from spruce and birch obtained by pressurised hot-water extraction and subsequent membrane ultrafiltration. Mass balances of the overall processes were calculated in respect to dry solids content and lignin content. The different lignin determination methods were evaluated according to the lignin mass balances obtained by the applied methods. The amount of lignin in the raw extracts and filtrates varied significantly depending on the used method. Nevertheless, thelignin mass balance calculations yielded similar results in general.
