摘要: 采用原位还原法将铂纳米颗粒负载到聚乙二醇修饰的氧化石墨烯表面（GO/PEG/Pt），此纳米杂化材料在水溶液中表现出较好的类过氧化物酶活性，能快速催化H₂O₂产生·OH，使显色底物3，3'，5，5'-四甲基联苯胺盐酸盐（TMB·2HCl）发生明显的颜色变化，在652 nm处出现吸收峰。当体系中引入汞离子（Hg²⁺）后，Hg²⁺被Pt⁰还原为Hg⁰，沉积在铂纳米颗粒表面，形成铂汞齐，导致GO/PEG/Pt表面活性位点被占据，使体系的信号输出被抑制，其抑制程度与Hg²⁺浓度呈线性关系。基于此原理构建了可即时检测Hg²⁺的可视化信号传感系统，在最佳实验条件下，其光谱分析检出限为3.96 nmol/L，裸眼检出限为10 nmol/L。将本方法用于检测自来水和湖水中的Hg²⁺，回收率在95.5%~108.6%之间，效果良好。

Abstract: Platinum nanoparticles were loaded onto the surface of poly(ethylene glycol)-modified graphene oxide (GO/PEG/Pt) via an in-situ reduction method. GO/PEG/Pt nanohybrids had excellent peroxidase-like activity in aqueous solution, and could catalyze H₂O₂ to produce ·OH rapidly, thus making the chromogenic substrate 3,3',5,5'-tetramethylbenzidine hydrochloride (TMB·2HCl) changed obviously and an absorption peak appeared at 652 nm in UV-Vis absorption spectrum. However, when the mercury ions (Hg²⁺) were introduced, Hg²⁺ was reduced to Hg⁰ by Pt⁰ and deposited on the surface of platinum nanoparticles to form platinum amalgam, which resulted in the occupation of surface-active sites of GO/PEG/Pt, the signal output of the system was inhibited, and the degree of inhibition varied linearly with Hg²⁺ concentration. Therefore, under the optimized experimental conditions, the visual colorimetric sensor was constructed to realize the sensitive analysis and real-time detection of Hg²⁺. The detection limit of spectral analysis was 3.96 nmol/L, and the detection limit of naked eye was 10 nmol/L. The method was applied to determination of Hg²⁺ in tap water and lake water, and the recoveries were between 95.5% and 108.6%.
