SummaryThe radionuclideIt was found that it is very difficult to create the same conditions present in the deep repository in the laboratory, which is why the reduction of the pertechnetate anion to its lower oxidation state (Tc(IV)) was not achieved. The retention of the pertechnate anion on bentonite is very low (
We report a novel way to improve the recognition of highly hydrated sulfate anions. It is shown that polyaniline (PANI) layer deposited on the poly(vinyl chloride) (PVC) membrane favors transport of highly hydrated anions due to stronger PANI hydration in their presence.
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.
