In the present paper, differential pulse voltammetry (DPV) techniques has been studied for monitoring of the concentration of oxalic acid (OA) during its electrochemical oxidation (EO) in acidic media at BDD anode applying a current of 60 mA cm 2 . Glassy carbon has been used for DPV measurements using two analytical procedures: calibration curves (DPVCC) and standard addition method (DPVSAM). DPV analyses have compared with classic titration method and HPLC achieving a good fit, confidence intervals and limits.

Abstract
In the present paper, differential pulse voltammetry (DPV) techniques has been studied for monitoring of the concentration of oxalic acid (OA) during its electrochemical oxidation (EO) in acidic media at BDD anode applying a current of 60 mA cm 2 . Glassy carbon has been used for DPV measurements using two analytical procedures: calibration curves (DPVCC) and standard addition method (DPVSAM). DPV analyses have compared with classic titration method and HPLC achieving a good fit, confidence intervals and limits.
