Adsorption behavior of aluminum compounds on pulp fibers at the wet-end was studied in terms of structures of aluminum components using some analytical techniques. Fibrous cellulose powder (CF) and fibrous carboxymethylcellulose powder (FCMC) were used as models of pulp fibers. When de-ionized water was used, aluminum components originating from alum added to cellulose suspensions were adsorbed on FCMC, probably forming carboxyl group aluminum salts. On the other hand, no interactions occurred between hydroxyl groups of cellulose and aluminum components in the suspensions. Analysis of adsorption behavior of cationic aluminum species on cellulosic fibers using solution-state ^27AI-showed that any cationic aluminum species such as AI^3+, AI_13.met^+7 and aluminum polymers were adsorbed on FCMC. Again no interactions were recognized between such cationic aluminum species and hydroxyl groups of cellulose in the ^27AI-NMR study. Thus, adsorption and retention behavior of aluminum compounds in paper is greatly influenced by carboxyl contents of pulp fibers used. Mapping analyses revealed that aluminum components were distributed almost homogeneously in the cross sections of each pulp fiber for the handsheets prepared with 2% aluminum sulfate or 2% polyhydroxyaluminum chloride (PHAC). Thus, water-soluble aluminum species such as AI^3+ ions, AI_13mer^7+' and aluminum polymers can penetrate into the inside pulp fibers during the handsheet-making process.
