Abstract:This work presents the results of a study of kinetic and adsorption isotherms of a cationic polyamine on bleached pulp of sugar cane bagasse. Polyamine was synthesized at laboratory scale and used in an experimental trial for the production of wet strength paper. In the isotherms and kinetic adsorption studies, pulp dispersions were used with the addition of KCl or aluminum sulfate. The concentration of the unadsorbed polyamine was determined by the polyelectrolyte titration. It was found that the polyamine ad… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
