Electrochemical Behavior and Voltammetric Determination of 2-Nitrophenol on Glassy Carbon Electrode Surface Modified with 1-Amino-2-Naphthol-4-Sulphonic Acid

2NP is among the priority pollutants for environmental ecosystem and poses a threat to health of living things by mixing in wastewater. Therefore, determination important. In this study, glassy carbon (GC) electrode surface was modified with 1-amino-2-naphthol-4-sulfonic acid (ANSA). The electrochemical behavior voltammetric 2-nitrophenol (2NP) on (ANSA-GC) performed. Firstly, it decided that supporting electrolyte medium suitable Britton-Robinson (BR) buffer effect pH change reduction peak environment investigated. changing scan rate examined study showed process ANSA-GC diffusion controlled process. For determination,two linear working ranges two different slopes, 1.19×10-6-1.66×10-4 M 1.66×10-4-1.14×10-3 were obtained. LOD LOQ values calculated as 0.29 µM 0.97 µM, respectively. Finally, lake water used real sample, determined water. experimental results can be high accuracy precision electrode.
