    Description / Table of Contents: Zusammenfassung Der Komplexbildner 1-(6-Chlor-3-indazolylazo)-2-hydroxynaphthalin-3,6-disulfosäure ist zum Nachweis von Spuren Co (grün), Cu (blau), Ni, Zn (violett) und Cd (rotviolett) geeignet. Erfassungsgrenze für diese Kationen bei Verwendung von 10 ml Probelösung: 0,5 μg, Verdünnungsgrenze: 1∶2 · 107. Der Kobaltnachweis ist unter geeigneten Bedingungen spezifisch. Für das neue Reagens wird der Trivialname „Chlorindazon DS“ vorgeschlagen.
    Notes: Abstract 1-(6′-Chloroindazole-3′-ylazo)-2-hydroxynaphthalene-3,6-disulphonic acid forms coloured complexes with cobalt (green), copper (blue), nickel (violet), zinc (violet), and cadmium (magenta), and can be used for detecting traces of these metals. Limit of detection, 0.5 μg; limit of dilution, 1∶2x107. Under suitable conditions the test for cobalt is specific. The name “Chloroindazon DS” is proposed for the reagent.
