Voltammetric determination of tinidazole in pharmaceutical tablets using carbon paste electrode
Cyclic voltammetry was used to study the electrochemical behavior of tinidazole at carbon paste electrode. Tinidazole showed an irreversible reduction peak at about -440 mV. The differential pulse voltammetric peak current of tinidazole showed linear dependence on concentration in the range 5.0-200...
