“…Lin, Ni, and Kokot made a simultaneous determination of the noxious nitroaniline isomers, by cyclic voltammetry (CV) and DPV, with the electro-polymerization of 7-[(2,4-dihydroxy-5-carboxybenzene)azo]-8-hydroxyquinoline-5-sulfonic acid (DHCBAQS) at a graphene-nafion-modified GCE, denoted at this work as, DHCBAQS/graphenenafion/GCE. The obtained LD was about 0.14 lmol dm -3 for all the compounds [15].…”

Differential pulse voltammetric determination of 4-nitroaniline using a glassy carbon electrode: comparative study between cathodic and anodic quantification

Differential pulse voltammetry with a glassy carbon electrode was used for the determination of trace amounts of 4-nitroaniline in Britton-Robinson buffer at pH 2.0 as an optimal base electrolyte. 4-Nitroaniline can be determined by differential pulse voltammetry directly using either its electrochemical oxidation or reduction. The calibration curve was measured for both reactions in the same concentration range from 2 to 100 lmol dm -3 . The calculated limits of detection and quantification are 0.2 and 0.7 lmol dm -3 (RSD 6.62 % and R 2 = 0.9906 for n = 5) for cathodic reduction and 0.3 and 1.0 lmol dm -3 (RSD 7.62 % and R 2 = 0.9995 for n = 5) for anodic oxidation.

A Hemin-f unctionalized electrochemically reduced graphene oxide (H-ERGO) nanocomposite was prepared for the construction of a nonenzymatic H 2 O 2 biosensor. H-ERGO was directly modified on the electrode surface without using a binder by electrochemical reduction. Detailed physical and electrical characterizations of H-ERGO were conducted by scanning electron microscopy, UV-vis absorption spectroscopy, and electrochemical impedance spectroscopy (EIS). Taking advantage of the superior catalytic properties of H-ERGO, we applied the proposed biosensor to H 2 O 2 analysis. Under optimized conditions, the H-ERGObased biosensor exhibited a wide linear range from 25 to 8850 and 8850 to 28850 μM, with a detection limit (S/N = 3) of 8.33 μM for H 2 O 2 determination. Furthermore, it was also successfully applied to detect H 2 O 2 in milk samples with recoveries ranging from 94.6 to 98.1%.
