Description

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.

Colorimetric response of dithizone product and hexadecyl trimethyl ammonium bromide modified gold nanoparticle dispersion to 10 types of heavy metal ions: understanding the involved molecules from experiment to simulation.

Yumin Leng et al.

Langmuir : the ACS journal of surfaces and colloids, 29(25), 7591-7599 (2013-06-04)

A new kind of analytical reagent, hexadecyl trimethyl ammonium bromide (CTAB), and dithizone product-modified gold nanoparticle dispersion, is developed for colorimetric response to 10 types of heavy metal ions (M(n+)), including Cr(VI), Cr(3+), Mn(2+), Co(2+), Ni(2+), Cu(2+), Zn(2+), Cd(2+), Hg(2+)

The Application of Nafion Metal Catalyst Free Carbon Nanotube Modified Gold Electrode: Voltammetric Zinc Detection in Serum.

Wei Yue et al.

Electroanalysis, 25(10), 2259-2267 (2014-01-18)

Metal catalyst free carbon nanotube (MCFCNT) whiskers were first used as an electrode modification material on a gold electrode surface for zinc voltammetric measurements. A composite film of Nafion and MCFCNT whiskers was applied to a gold electrode surface to
