Antimony (Sb) is a heavy metal widely found in water environment and has been continuously proven to pose chronic toxicity and carcer risks to humans and wildlife. The establishment of rapid and highly sensitive analytical methods or the detection of Sb is of crucial importance in the monitoring and management of Sb pollution in the water environment. This article summarized the progress and applications of various analytical methods for Sb analysis, including spectrophotometry, atomic fluorescence spectroscopy (AFS), inductively coupled plasma-mass spectrometry (ICP-MS), nductively coupled plasma optical emission spectrometry (ICP-OES), atomic absorption spectroscopy (AAS), and electrochemical analysis. It also discussed the challenges and issues associated with Sb detection in water environments, such as low sensitivity of detection methods, time-consuming and inaccurate indirect determination of Sb, and the relative cost and oxicity of reducing agents. The future development direction of Sb detection is prospected. The emerging trend for Sb detection is the development of electrochemical analysis methods. Sensor performance is improved by electrode modification and nanomaterial design, such as carbon-based materials, metal nanoparticles and silicon-based materials. Functionalization of organic ligands, nanocomposites and bare electrodes can enhance sensitivity and promote sensor miniaturization. The future of Sb detection will move towards miniaturization, chip-based systems and rapid analysis. [ABSTRACT FROM AUTHOR] |
