Abstract:The possibility of simultaneous polarographic determination of two metals with azo dyes (eriochrome blue SE, kalces, eriochrome red B, eriochrome black T) was studied. The following metals were investigated: Al(III), Sc(III), Ga(III), In(III), and REE(III). The optimal conditions for the determination of different combinations of these metals were established. The main factor determining the possibility of simultaneous analysis is the pH of the medium, and appropriate values of pH for the determination of diff… 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.
