    Abstract: Water pollution incidents happen frequently in recent years. Heavy metal ions can be absorbed by the human body through the food chain and threat the health of human being. It is of great practical significance to monitor heavy metal ions. Anodic stripping method is one of the suitable methods for on-site heavy metal ions monitoring, because of its high accuracy and easy operation. In this paper, paper-based sensing electrode chip was fabricated on nitrocellulose blotting membrane by magnetron sputtering technology. This electrode has three-dimensional surface microstructure, which is beneficial to achieve high sensitivity detection without film modification. Using this paper-based sensing electrode for Cu2+ detection by Square Wave Voltammetry (SWV), good linear relationship was displayed in the range of 5—1000 μg·L-1 with the limit of detection of 2 μg·L-1.
