Abstract:The possibility of bioaccumulation of uranium and thorium species in the blue-green algae Azolla caroliniana Willd. was investigated. The behavior of the Azolla caroliniana-* M n+ (* M n+ = UO 2 2+ , Th 4+) system was studied versus contact time, pH and anion nature with no ionic competition. The effective UO + 2 2 and Th 4+ ions removal from low radioactive waste waters was demonstrated. The analysis of the data revealed the following optimum working conditions: for uranium: contact time 20 hours, pH = 6.0, t… 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.
