Abstract:The
effects of selenium species on the Belousov–Zhabotinsky
(B–Z) reaction were investigated by adding them to the system
before and during oscillation. When selenium species were added into
the system before oscillation, sodium selenite prolonged the induction
period, whose effect was strong as sodium selenite could consume malonic
acid to prohibit the accumulation of bromomalonic acid. For selenomethionine
and selenocystine, their effects were derived from their reaction
with •CH2COOH and •Br2
– producing a … 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.
