Beschreibung

Allgemeine Beschreibung

Dithizone (Diphenylthiocarbazone) is used as chelating agent for zinc. It is widely used for the liquid-liquid and solid phase extraction of various metals since it forms stable complexes with the metals.

Anwendung

Indikator für Metalle.

Dithizone (Diphenylthiocarbazone) may be used in the following studies:

• In the cloud point preconcentration step, before the trace level quantification of silver by flame atomic absorption spectrometry.
• Preparation of hexadecyltrimethyl ammonium bromide (CTAB) capped gold nanoparticles (AuNPs). This reagent was useful for the colorimetric detection of heavy metal ions.
• As a zinc chelating ligand for the extraction of zinc in bovine serum.

Dithizone has been used in the preparation of dithizone stain solution for pancreatic islet cells.
