An electrochemical sensor for cadmium ion detection that is based on an AuNP-functionalized metal–organic framework-graphene nanocomposite
Source abstract
Abstract
A Zn metal–organic framework (MOF5) was synthesized successfully by using a simple hydrothermal method. A carbon paste (CP) electrode was modified by utilizing a gold nanoparticle-functionalized MOF5/graphene layer (AuNP@Gr/MOF5 nanocomposite). The AuNP@Gr/MOF5 layer was characterized using FTIR, SEM, EDX, TEM, and XRD. The AuNP@Gr/MOF5 nanocomposite-modified electrode was used for the determination of Cd+2ions in 0.1 M acetate buffer at pH 4.5 using the SWV technique. The developed sensor exhibited linear behavior in the concentration range of 0.01–30 μM with a limit of detection of 0.005 μM. A good recovery percentage of 88–102% was achieved in real wastewater samples. The developed sensor showed high selectivity, reducibility, and stability.Graphical abstract
