Abstract:Reccebido em 2/3/01; aceito em 26/7/01 USE OF REAGENT IN SUSPENSION IN FLOW INJECTION ANALYSIS. SPECTROPHOTOMETRIC DETERMINATION OF SULPHATE IN NATURAL WATER. This paper presents an automatic procedure employing a reagent in the form of a slurry in a flow-injection system. The feasibility of the proposal is demonstrated by sulphate determination in water using the Barium Chloranilate method, which is based on the precipitation of barium sulphate. The release of a stoichiometric amount of highly colored chloran… 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.
