Dithizone-functionalized C

This study focuses on dithizone-functionalized c. The research employs high-performance liquid chromatography (HPLC) techniques to address analytical challenges in the environmental field. A simple and efficient dithizone-functionalized solid-phase extraction (SPE) procedure, online coupled with high-performance liquid chromatography (HPLC)-inductively coupled plasma mass spectrometry, was developed for the first time for enrichment and determination of ultra-trace mercury (Hg) species (inorganic divalent Hg (Hg(II)), methylmercury (CH... Research Background and Significance Mercury contamination remains a critical environmental issue due to its toxicological effects and bioaccumulative nature in ecosystems. Accurate detection and speciation of mercury species such as inorganic divalent mercury (Hg(II)) and methylmercury (CH3Hg+) at ultra-trace levels are essential for environmental monitoring and risk assessment. Traditional analytical approaches often face challenges including low sensitivity, matrix interferences, and complex sample preparation. The study by Wang et al. (2022) introduces a novel dithizone-functionalized solid-phase extraction (SPE) technique online coupled with high-performance liquid chromatography (HPLC) and inductively coupled plasma mass spectrometry (ICP-MS). This approach aims to enhance enrichment and selective determination of mercury species with improved analytical performance, addressing significant limitations in current mercury speciation methods. The integration of a functionalized SPE with sensitive chromatographic separation provides a promising analytical platform for environmental scientists and regulatory agencies.
