Through simple high-temperature hydrothermal treatment of carbon cloth, a hoCCE electrochemical sensor wasprepared for detecting Pb2+. After hydrothermal treatment, the carbon cloth surface has more ketone-based sitesand defects, which improves the electrochemical active area, conductivity and detection sensitivity, andstrengthens the catalytic performance of Pb2+. Under optimal conditions, the current concentration curve wasobtained by differential pulse anodic stripping voltammetry, with linear range 0.06 - 1.6 μM, regression equationIp(mA) = 0.03208 + 0.12843C (μM), and detection limit 30 nM. The resulting sensor was applied to detect Pb2+ inreal-life water samples. Compared with other studies, hoCCE enjoys advantages in linear interval detection, cost,preparation procedure, and vulnerability.
