“…This allows one to determine the adsorption characteristics during the initial polymer/colloid contact period when the polymer concentration in the bulk solution is maximal and at succeeding time points as the polymer concentration in the mobile phase progressively decreases and finally drops to that measured in the effluent [22]. Injection of a second polymer into the column and determination of the new adsorption characteristics provides information on the modifications to the bare adsorbent induced by the first polymer and on the changes induced by these modifications in the interactions between the interface and the second polymer [23]. In Refs.…”

“…In Refs. [22,23], the authors studied polyvinylamine of different molecular weights and/or hydrolysis grades for which the interactions with a silica adsorbent were found to be of a similar nature. In Ref.…”

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.
