General description
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.
Application
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.
