Electrochemical real-time sensor for the detection of Pb(II) ions based on TiCT MXene.

Lead ions are especially harmful to human health, causing significant developmental and behavioral abnormalities even at small concentrations. In real-life samples, lead ions are present in mixtures with other metal ions, creating a challenge to detect it selectively at low quantities. To address these challenges, we prepared an electrochemical sensor based on delaminated TiCT MXene, which can selectively detect low concentrations of Pb in a solution containing other common metal ions.
