摘要：

A core-shell structured magnetic nano-composite Fe3O4@PPy, synthesized by the chemical oxidative method and the electrochemical behavior of the composite assessed under different conditions. The modified Fe3O4@PPy/GC electrode employed to determine the 2-aminophenol (2AMP) by cyclic voltammetry (CV), differential pulse voltammetry (DPV), and chrono-amperometry (CA). 2AMP exhibited cathodic peak on the Fe3O4@PPy/GC electrode. The linear response observed for 2AMP in the concentration range (50 to 450 nM; CV, 50 to 450 nM; DPV and 50-300 nM; in amperometry). The limit of detection (CV; 15nmol L-1, DPV; 16.5 nmol L-1 and 4 nmol L-1 in amperometry) with a limit of quantification (CV; 45 nmol L-1, DPV; 49.5 nmol L-1 and up to 50nmol L-1 in amperometry), respectively, on the modified electrode.
