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 modified silver electrode for the determination of metal ions in aqueous solution: This study discusses a dithizone-modified electrode used for the electrochemical determination of various metal ions, highlighting its applications in environmental monitoring and industrial process control (Othman et al., 2016). Source.
- Eco-friendly immobilization of dithizone on coal bottom ash for the adsorption of lead (II) ion from water: This study explores the use of dithizone-immobilized coal ash for the efficient removal of lead from water, demonstrating a cost-effective method for treating contaminated water (Huda et al., 2021). Source.
- Colorimetric Sensing of Pb2+ Ion by Using Ag Nanoparticles in the Presence of Dithizone: The article details the development of a colorimetric sensor for lead ions, which uses silver nanoparticles and dithizone, providing a rapid and sensitive method to detect heavy metal contamination in environments (Roto et al., 2019). Source.
- Dithizone-etched CdTe nanoparticles-based fluorescence sensor for the off–on detection of cadmium ion in aqueous media: This research presents a fluorescent sensor based on dithizone-etched CdTe nanoparticles for detecting cadmium ions, offering applications in environmental monitoring and safety assessments (Li et al., 2017).
