Environmental status of cobalt and its microdetermination with 7-nitroso-8-hydroxyquinoline-5-sulfonic acid in waters, aquatic weeds and animal tissues
Journal Article
·
· Anal. Lett.; (United States)
A method is presented for the spectrophotometric microdetermination of cobalt (II) in fresh waters, aquatic weeds, and animal tissues employing 7-nitroso-8-hydroxy-quinoline-5-sulfonic acid. The method enables direct determination of cobalt (II) in presence of a large number of anions and cations commonly associated with cobalt, and is adequate for determining the metal in the concentration range of 0.001-10 ppm, which is commonly encountered in environmental samples.
