摘要：

本文研究了金纳米颗粒@碳微球(Au@CMSs)的制备及水环境中汞离子在该材料上的电化学行为. 实验结果表明，在0.1 mol•L^-1 pH = 5.0的NaAc-HAc缓冲溶液中，采用方波伏安法测定汞离子，其浓度与氧化峰电流强度线性良好，相关系数为0.997，检出限为3.69 × 10^-8 mol•L^-1（3σ方法）.

关键词: 金纳米颗粒@碳微球, 方波伏安法, 电化学测汞离子

Abstract:

The gold nanoparticles@carbonaceous microspheres (Au@CMSs) and Au@CMSs modified glassy carbon electrode (GCE) were prepared. The Au@CMSs modified GCE was further examined for possible sensitive detection of mercury ions (Hg(II)) in an aqueous solution by square wave anodic stripping voltammetry (SWASV). The excellent performance was found in the stripping analysis of Hg(II) in 0.1 mol•L^-1 NaAc-HAc(pH=5.0) with a sensitivity of 25.863 A•(mol•L^-1)^-1 and a detection limit of 3.69×10^-8 mol•L^-1 based on the 3σ method.

Key words: Hg(II), anodic stripping voltammetry, carbonaceous microspheres
