Bismuth Nanoparticles Decorated Vertically Arranged Graphene as Flexible Electrodes for Highly Efficient Detection of Pb(Ii) Ions in Water

SSRN Electronic Journal (2022)

Lin He Chunwen Chang Qiang Xue Xizhou Zhong Xin Zhao

Plasma enhanced chemical vapor deposition (PECVD) system was used to prepare a vertically arranged graphene(VG) thin-film materials. Bismuth nanoparticles (BiNPs) of different sizes were loaded on VG films by physical vapor deposition (PVD) technique to obtain a BiNPs decorated VG screen-printed electrodes (BiNPs/VG-SPEs) with high sensitivity. The morphology and electrochemical properties of VG-SPE and three BiNPs/VG-SPEs with different sizes of BiNPs were studied by various interface characterization and electrochemical measurements. Compared with pristine VG-SPEs, BiNPs/VG-SPEs demonstrated better electrochemical performance. The electrode with smaller size of BiNPs has the larger electrochemical active area and higher electron transfer efficiency, achieving better electrochemical response to Pb(II) ions. Therefore, VG-SPE with smallest size of BiNPs (4.6 ± 0.5 nm) was utilized to detect Pb(II) ions in aqueous solution. Under the optimized conditions, BiNPs/VG-SPE showed a broader linear concentration range (5-200 μg/L) with a low detection limit ( 0.15 ug/L ). This sensor was also successfully applied for detection of Pb(II) ions in groundwater and tap water. Recovery rates ranged from 96.2 to107.2% with a relative standard deviation (RSD) less than 6.8%. It also has good anti-interference and repeatability. Our results provide a promising sensor technique for efficient and rapid in situ monitoring of Pb(II) ions in aquatic environments.

Recent progress regarding electrochemical sensors for the detection of typical pollutants in water environments

Analytical Sciences (2021)

Yao Liu Qiang Xue Chunwen Chang Rong Wang Zeyu Liu

A variety of organic and inorganic pollutants in water environments pose threats to human health. Therefore, it is critical to develop effective techniques to determine and monitor the levels of water contamination. Compared to traditional detection methods, electrochemical sensors have the advantages of high sensitivity, low detection limits, and good selectivity. In this review, we summarize the progress made from 2000 to 2020 regarding the development of electrochemical sensors capable of detecting typical pollutants in different water environments. Since the concentrations of typical organic contaminants (antibiotics and pesticides) in water environments are often very low (generally at the nmol level), further improvements to the electrode sensitivity and detection limit will be necessary. We also found that more detailed cost analysis of electrode materials is needed to support future production and applications. When we apply the electrode to detect real water samples, the anti-interference and electrochemical sensor componentization need to be further enhanced. Besides, although groundwater serves as the main, or only, source of drinking water in many areas, current studies on the electrochemical detection of groundwater pollutants are limited. We hope that this review will provide new ideas for the future development of electrochemical water contaminant sensors.
