Concerns over exposure to mercury have motivated the exploration of cost-effective, rapid, and reliable method for monitoring Hg(2+) in the environment. Recently, surface-enhanced Raman scattering (SERS) has become a promising alternative method for Hg(2+) analysis. SERS is a spectroscopic technique which combines modern laser spectroscopy with the optical properties of nano-sized noble metal structures, resulting in substantially increased Raman signals. When Hg(2+) is in a close contact with metallic nanostructures, the SERS effect provides unique structural information together with ultrasensitive detection limits. This review introduces the principles and contemporary approaches of SERS-based Hg(2+) detection. In addition, the perspective and challenges are briefly discussed.
对汞暴露的担忧促使人们探索经济高效、快速且可靠的环境中汞离子（Hg(2+)）监测方法。最近，表面增强拉曼散射（SERS）已成为一种有前景的汞离子分析替代方法。SERS是一种光谱技术，它将现代激光光谱学与纳米级贵金属结构的光学特性相结合，从而大幅增强拉曼信号。当汞离子与金属纳米结构紧密接触时，SERS效应可提供独特的结构信息以及超灵敏的检测限。本文综述介绍了基于SERS的汞离子检测原理和当代方法。此外，还简要讨论了前景和挑战。
