Preparation of Ag/PANI/GCE Electrode and Application in the Electrochemical Determination of NO2-

Keywords： polyaniline , nano Ag , NO2- , electrochemical determination

亚硝酸盐是水中最常见的污染物之一,其检测长期以来一直是国内外研究的热点问题.制备了聚苯胺载银修饰玻碳电极(Ag/PANI/GCE)并将其应用于水中亚硝酸根的电化学检测.初步研究了亚硝酸根在电极表面的电化学行为的影响因素,并分析了所制备电极材料检测亚硝酸根的灵敏度、稳定性以及抗干扰性能.结果显示,所制备的Ag/PANI/GCE电极材料的电化学稳定性好,可以对水中的亚硝酸根浓度进行有效的检测,同时具有稳定性好、灵敏度较高、抗干扰性能强等优势,具有较高的研究价值和较好的应用前景.
