Abstract

The voltammetric behavior of niflumic acid (HNIF) in the presence and absence of vanadium (V) was investigated using square-wave (SW) voltammetry at physiological pH. SW voltammogram of HNIF exhibited only one cathodic peak at -0.998 V. Due to the complex formation between metavanadate (VO3-, abbreviated as MV) and HNIF, a cathodic signal was observed at -1.228 V. According to the electrochemical results, the stoichiometry of V(V) complex was found to be 1:1. The spectroscopic characterization of the synthesized solid powder V(V)-NIF complex was also carried out.
