Abstract:Based on the former experience on the design and construction of metal ions sensors, especially those of high sensitivity for lanthanides, (2-oxo-1,2-diphenylethylidene)-N-phenylhydrazinecarbothioamide (PHCT) was used to construct a Lu 3+ PVC sensor exhibiting a Nernstian slope of 19.8±0.3 mV dec -1 . The sensor was found to function well over a concentration range of 1.0×10 -2 and 1.0×10 -6 mol L -1 of the target ion with a detection limit of 6.8×10 -7 mol L -1 . The sensor selectivity against many common alk… 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.
