Abstract

An electrochemical sensor for Cu(II) based on ion-imprinted polymers was prepared by combining surface imprinting with electrochemical polymerization deposition. The sensor was modified by ion-imprinted magnetic carbon nanospheres with a specific selectivity and sensitivity for Cu(II). The morphology and structure of the materials were characterized and analyzed. Sensors with the imprinted electrode had a stronger selectivity and higher sensitivity towards Cu(II) compared with their original counterparts. Within relative concentrations of Cu(II) from 10⁻⁶ to 10⁻¹⁰ mol L⁻¹, the detection limit of the sensor was as low as 5.138×10⁻¹⁶ mol L⁻¹ (S/N=3). The sensor is resistant to interference, and has good reproducibility, and stability, making it excellent for the electrochemical detection of metal ions.

基于离子印迹磁性纳米碳球的高选择性、高灵敏度电化学铜(II)检测器

通过将表面印迹法与电化学聚合沉积法相结合，制备了一种基于离子印迹聚合物的铜（II）电化学传感器。该传感器由离子印迹磁性纳米碳球修饰，对 Cu(II)具有特定的选择性和灵敏度。对材料的形态和结构进行了表征和分析。与原来的传感器相比，带有印迹电极的传感器对 Cu(II)具有更强的选择性和更高的灵敏度。在 10-6 至 10-10 mol L-1 的铜(II)相对浓度范围内，传感器的检测限低至 5.138×10-16 mol L-1 （S/N=3）。该传感器具有抗干扰性、良好的重现性和稳定性，非常适合金属离子的电化学检测。

期刊介绍： New Carbon Materials is a scholarly journal that publishes original research papers focusing on the physics, chemistry, and technology of organic substances that serve as precursors for creating carbonaceous solids with aromatic or tetrahedral bonding. The scope of materials covered by the journal extends from diamond and graphite to a variety of forms including chars, semicokes, mesophase substances, carbons, carbon fibers, carbynes, fullerenes, and carbon nanotubes. The journal's objective is to showcase the latest research findings and advancements in the areas of formation, structure, properties, behaviors, and technological applications of carbon materials. Additionally, the journal includes papers on the secondary production of new carbon and composite materials, such as carbon-carbon composites, derived from the aforementioned carbons. Research papers on organic substances will be considered for publication only if they have a direct relevance to the resulting carbon materials.
