Abstract:The adsorption rate of the cationic surfactant cetyl trimethylammonium bromide (CTAB) onto particles of activated carbon has been determined from measurements of the changes in the conductivity of the supernatant solution. This technique exhibited a high sampling frequency which enabled detailed analysis of the adsorption kinetics. It was demonstrated that the adsorption rate was generally positively correlated with the stirring rate, although the effect was small. The adsorption rate could be modelled by 1.3-… 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.
