Synthesis and characterization of polypyrrole decorated graphene/β-cyclodextrin composite for low level electrochemical detection of mercury (II) in water

tMercury (Hg(II)) is considered as one of the most toxic element that directly affects the human healthand the environment. Therefore, in this study, we propose a sensitive and disposable electrochem-ical sensor for the detection of Hg(II) in various water samples using polypyrrole (PPy) decoratedgraphene/-cyclodextrin (GR-CD) composite modified screen-printed carbon electrode (SPCE).
