Abstract
In this paper, a novel poly(aminosulfonic acid) modified glassy carbon electrode (PASA/GCE) for the determination of Sudan II was fabricated through electrochemical polymerizat ion. The electrochemical behavior of Sudan II at the modified electrode was studied by cyclic voltammetry. Results show that the modified electrode exhibits excellent electrocatalytic activity toward the electrochemical redox reaction of Sudan II. Under optimal experimental conditions, the oxidation peak current is linearly proportional to the concentration of Sudan II in the ranges of 4.0 × 10−8 to 1.0 × 10−6 mol L−1 and 1.0 × 10−6 to 1.2 × 10−5 mol L−1. The linear regression equations are i pa(A) = 2.87c + 3.74 × 10−6, r = 0.9977 and i pa(A) = 0.78c + 6.11 × 10−6, r = 0.9982, respectively, and the detection limit is 4.0 × 10−9 mol L−1. The novel method shows good recovery, reproducibility and sensitivity for the voltammetric determination of Sudan II in food samples.
