研究目的
Investigating the therapeutic effects of a specific herbal medicine on a particular disease.
研究成果
GO-based HMS have been successfully fabricated and tested. The presence of GO has contributed significantly to heavy metal ions detection. The sensor showed higher sensitivity towards Pb ions compared to Hg and Cd. Further improvements of the sensor can be sought in the future.
研究不足
The study focused on the detection of heavy metal ions using GO as the sensing element. The sensitivity towards different heavy metal ions varied, with Pb showing the highest sensitivity and Hg the least. The study did not explore the detection of other heavy metals or the optimization of the sensor for real-world applications.
1：Experimental Design and Method Selection:
The study involved the fabrication of a heavy-metal-ion sensor (HMS) using graphene oxide (GO) as the sensing element. The HMS employed a three-electrode configuration architecture.
2：Sample Selection and Data Sources:
GO of various concentrations ranging from
3：1 to 1 mg/ml was prepared by probe sonicating freeze-dried GO flakes in DI water. Heavy metal ions such as lead (Pb), mercury (Hg), and cadmium (Cd) were used. List of Experimental Equipment and Materials:
The sensor was connected to a potentiostat (μAutolabIII) for cyclic voltammetry measurements.
4：Experimental Procedures and Operational Workflow:
About 20 μL of the heavy metal-ion solution was dropped onto the HMS, covering all three electrodes.
5：Data Analysis Methods:
The sensing performance was analyzed based on the sensitivity towards different heavy metal ions.
