Electrochemical behavior of para-nitroaniline at a new synthetic crown ether-silver nanoparticle modified carbon paste electrode

摘要

A new synthetic ligand (6,7,9,10,17,18,19,20,21,22-decahydrodibenzo[h,r][1,4,7,11,15] trioxadiazacyclonanodecine-16,23-dione, DTD)–Ag nanoparticles (AgNP) modified carbon paste electrode (DTD/Ag–CPE) is fabricated. Voltammetric behavior and determination of para-nitroaniline (PNA) is explored. The influence of various experimental parameters on the electrode response is investigated. Under optimized conditions the peak current showed a good linear relationship with p-nitroaniline concentration in the range 1 × 10?6 mol L?1 to 1 × 10?4 mol L?1. The proposed electrode was applied to p-nitroaniline determination in water samples...
