Abstract: Hemicelluloses (I) can be removed from the brown liquor of viscose fiber by pptn. with CuSO4 or less effectively by Pb(OAc)2, Ca(OH)2, Ca(OAc)2, Al(ONa)3, and Ba(OH)2 or by chemisorption on powd. Ca(OH)2 and active C (II). The max. adsorption of I was 79.2% if the ratio of II to NaOH is 1:8.
