Gold nanoparticles decorated carbon fiber mat as a novel sensing platform for sensitive detection of Hg(II)
چکیده انگلیسی


• A facile and sensitive Hg(II) sensor platform was constructed.
• The platform is easy to fabricate in comparison with other solid electrode.
• The sensing platform displayed high sensitivity and good reproducibility.

The three-dimensional fibril-like carbon fiber mat electrode (CFME) decorated with Au nanoparticles (AuNPs) was employed to construct Hg(II) sensing platform for the first time. The highly porous feature of CFME combining the high affinity of AuNPs for mercury endowed the sensing platform with high sensitivity and good reproducibility. Under optimal conditions, the prepared AuNPs/CFME was capable of sensing Hg(II) with a detection limit of 0.1 μg L− 1 (S/N = 3) using differential pulse anodic stripping voltammetry (DPASV). Finally, the AuNPs/CFME was successfully demonstrated for the determination of Hg(II) in real water samples with satisfactory results.
