چکیده
|
A carbon paste electrode modified with nio nanoparticles (cpe-m-nio/nps) was fabricated and used as a high performance sensor for nitrite (nt). cpe-m-nio/nps was prepared by mixing nio/nps,graphite powder and liquid paraffin together. the cpe-m-nio/nps showed electrocatalytic activity to the electro-oxidation of nt,and an irreversible oxidation peak appeared at 0.90 v with improved peak current. the linear response range was found to be 0.8–1100 μm. detection limit (3σ) of nt was found to be 0.3 μm by square wave voltammetry (swv) method. the cpe-m-nio/nps was successfully applied for the determination of nt in food samples. © 2016 by cee (center of excellence in electrochemistry).
