摘要
锑(Sb)是广泛存在于水环境中的一种重金属,不断被证实对人和动植物等有慢性毒性和致癌风险。在监测和治理水环境中的Sb污染方面,建立快速、高灵敏度的Sb检测分析方法至关重要。重点阐述了分光光度法、原子荧光光谱法(AFS)、电感耦合等离子体质谱法(ICP-MS)、电感耦合等离子体原子发射光谱法(ICP-OES)、原子吸收光谱法(AAS)和电化学分析法在Sb分析检测中的相关研究及应用进展,探讨了水环境中Sb检测存在的问题和面临的挑战,如检测方法灵敏度低、间接测定Sb耗时且不准确、还原剂昂贵且有毒等。此外,对Sb检测未来的发展方向进行展望。未来Sb检测趋势是发展电化学分析方法。通过电极修饰和纳米材料设计提高传感器性能,如碳基材料、金属纳米颗粒和硅基材料。有机配体、纳米复合材料和裸电极的功能化可增强灵敏度和选择性,促进传感器小型化。未来Sb检测将迈向小型化、芯片化和快速化。
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 for 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),inductively 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 toxicity 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 selectivity and promote sensor miniaturization.The future of Sb detection will move towards miniaturization,chip-based systems and rapid analysis.
