| description | The high-performance determination of heavy metal ions (Cd<sup>2+</sup>) in water sources is significant for the protection of public health and safety. We have developed a novel sensor of nanograss boron and nitrogen co-doped diamond (NGBND) to detect Cd<sup>2+</sup> using a simple method without any masks or reactive ion etching. The NGBND electrode is constructed based on the co-doped diamond growth mode and the removal of the non-diamond carbon (NDC) from the NGBND/NDC composite. Both the enlarged surface area and enhanced electrochemical performance of the NGBND film are achievable. Scanning electron microscopy, Raman spectroscopy, X-ray photoelectron spectroscopy, cyclic voltammetry, electrochemical impedance spectroscopy, and differential pulse anodic stripping voltammetry (DPASV) were used to characterize the NGBND electrodes. Furthermore, we used a finite element numerical method to research the current density near the tip of NGBND. The NGBND sensor exhibits significant advantages for detecting trace Cd<sup>2+</sup> via DPASV. A broad linear range of 1 to 100 μg L<sup>−1</sup> with a low detection limit of 0.28 μg L<sup>−1</sup> was achieved. The successful application of this Cd<sup>2+</sup> sensor indicates considerable promise for the sensitive detection of heavy metal ions. |
