摘要

在此，我们报道了一种基于钯的电化学传感器，用于阴极溶出伏安法(CSV)检测高电负性锰(Mn)。该传感器的独特之处在于将电镀钯(Pd)工作电极和辅助电极集成在铜(Cu)衬底上，采用新的Cu/CuCl2参考电极，从而降低了成本并简化了制造过程。该传感器在硼酸盐缓冲液中具有良好的线性响应，检出限为330nM (18.6ppb)。该传感器还成功地测量了河水中的锰，并最终可能扩展到其他环境样品矩阵。

Palladium-based sensor for electrochemical detection of manganese in the environment

Herein, we report a palladium-based electrochemical sensor for cathodic stripping voltammetry (CSV) detection of highly electronegative manganese (Mn). The unique aspect of the sensor is the integration of electroplated palladium (Pd) working and auxiliary electrodes on copper (Cu) substrate with a new Cu/CuCl2 reference electrode, which reduces cost and simplifies fabrication. The sensor was fully characterized and was found to exhibit a linear response in borate buffer with limit of detection (LOD) of 330nM (18.6ppb). The sensor also demonstrated successful measurement of Mn in river water, and ultimately may be extended to other environmental sample matrices.
