Indirect determination of dopamine and paracetamol by electrochemical impedance spectroscopy using azo coupling reaction with oxidized 2,4-dinitrophenylhydrazine (DNPH): Application in commercial tablets
A new method for the determination of dopamine (DA) and paracetamol (PCT), based on the azo “coupling reaction with oxidized 2,4 dinitrophenylhydrazine (DNPH), has been established. This method was based on the fact that in the HCl buffer solution, potassium ioadate oxidized 2,4- dinitrophenylhydraz...
