Abstract

Excessive nitrate accumulation in soil and water has become a critical environmental concern, threatening ecosystems and public health. This drives the need for designing new electrochemical nitrate sensors based on novel electroactive materials. In this work, we synthesized a hybrid film material composed of poly 1,8-diaminonaphthalene and copper oxide particles electrodeposited on the surface of a carbon paste electrode (Cu2O–CuO/poly 1,8-DAN/CPE). The electrodeposition of the polymer was conducted in galvanostatic mode at a positive current, followed by the electrodeposition of copper in potentiostatic mode at a negative potential. The polymeric film obtained through this facile electropolymerization method showed a uniform dispersion of copper particles and could improve the mechanical stability of the fabricated sensors, thereby leading to a low detection limit of nitrate ions. The Cu2O–CuO/poly 1,8-DAN/CPE was prepared in just 3 min in both the galvanostatic and potentiostatic mode. The developed sensor exhibited a good electrochemical performance for nitrate ions, with a linear range from 2 to 200 μM, strong stability, high reproducibility, and a low detection limit of 0.5 μM. This work revealed that the deposition of polymer can be applied as a promising material in new applications, such as water denitrification.

通过基于聚1,8-二氨基萘和氧化铜颗粒膜的电化学传感器进行简单和高灵敏度的硝酸盐离子检测。
硝酸盐在土壤和水中的过量积累已成为一个严重的环境问题,威胁着生态系统和公众健康。这推动了基于新型电活性材料设计新型电化学硝酸盐传感器的需求。在这项工作中,我们合成了一种由聚1,8-二氨基萘和氧化铜颗粒电沉积在碳糊电极(cu20 - cuo /聚1,8- dan /CPE)表面的杂化薄膜材料。聚合物的电沉积是在正电流的恒流模式下进行的,然后在负电位的恒电位模式下进行铜的电沉积。通过这种简便的电聚合方法获得的聚合物膜显示出铜颗粒均匀分散,可以提高所制备传感器的机械稳定性,从而导致硝酸盐离子的低检测限。cu20 - cuo /聚1,8- dan /CPE在恒流和恒电位两种模式下均在3 min内制备完成。该传感器对硝酸盐离子具有良好的电化学性能,线性范围为2 ~ 200 μM,稳定性强,重现性高,检出限低至0.5 μM。研究结果表明,聚合物沉积在水脱氮等新领域具有广阔的应用前景。
