英文摘要poly(p-aminobenzene sulfonic acid)-modified graphite electrode [poly(p-absa)/ge] was prepared via a straightforward one-step electropolymerization and was employed to investigate the electrochemical behavior of o-nitrophenol (o-np), m-nitrophenol (m-np) and p-nitrophenol (p-np), for the purpose of realizing the simultaneous determination of nitrophenol isomers. semi-derivative voltammetry (sdv) was adopted to enhance the resolution and sensitivity. compared with the bare ge, poly(p-absa)/ge exhibited excellent electrocatalytic activity towards the oxidation process of the intermediate products of nitrophenol isomers. thus, o-, m- and p-np can be clearly identified and successfully separated at 0.119v, -0.125v and 0.027v (vs. saturated calomel electrode). under the optimized experimental conditions, the linear ranges of the calibration curves were 3 similar to 800 mu mol l-1 for o-np, and 3 similar to 700 mu mol l-1 for both m-np and p-np. in addition, the low detection limits for o-, m- and p-np were 0.28, 0.5 and 0.3 mu mol l-1, respectively (s/n = 3). the proposed method is novel and has many advantages such as simple, sensitive, selective, reproducible and cost-effective. therefore, it can be considered a promising sensing platform for direct simultaneous determination of nitrophenol isomers in water samples.
