由于对人类和动物的毒性，地下水中的重金属和硝酸盐受到特别关注。由于其高毒性和广泛分布，迫切需要对土壤孔隙水和浅层地下水中硝酸盐和重金属进行有效的监测和测量。在这项工作中，开发了一种新的电化学传感平台，该平台具有自组装纳米球填充（nBP）异质柱，用于pH和硝酸盐的测量。此外，为了现场检测镉（Cd(II)），设计、制作了一种基于方波阳极溶出伏安法（SWASV）传感原理的铋（Bi(III)）基聚合物实验室芯片传感器，并成功地进行了表征。研究了影响传感器灵敏度和精度的因素，包括沉积电位和沉积时间。小型化电化学实验室芯片传感器具有传感成本低、传感系统便携、易于使用等优点，在环境监测领域具有重要的应用价值。
Due to their toxicity to humans and animals, heavy metals and nitrate in groundwater are of particular concern. The combination of high toxicity and widespread occurrence has created a pressing need for effective monitoring and measurement of nitrate and heavy metals in soil pore water and groundwater at shallow depths. In this work, a new electrochemical sensing platform with the self-assembly nanobeads packed (nBP) hetero columns has been developed for the pH and nitrate measurements. In addition, for on-site determination of cadmium (Cd(II)), a bismuth (Bi(III)) based polymer lab chip sensor using the square-wave anodic stripping voltammetry (SWASV) sensing principle has been designed, fabricated and successfully characterized. Factors affecting sensitivity and precision of the sensor, including deposition potential and deposition time, were studied. Miniaturized electrochemical lab chip sensors could be very valuable in environmental monitoring area due to their many benefits, such as greatly reduced sensing cost, sensing system portability, and ease of use.
