Abstract
The carbon paste electrode was modified by nevirapine drug, the voltammetric behaviour of paracetamol and folic acid at modified carbon paste electrode were investigated by cyclic voltammetric technique. The modified nevirapine carbon paste electrode showed an enhanced sensitivity towards paracetamol and folic acid. The modified nevirapine electrode had strong resolving capacity for overlapping voltammetric response of paracetamol and folic acid into two well resolved peaks, with increment of peak current as compared to the bare carbon paste electrode. The simultaneous determination of paracetamol in presence of folic acid without any interference is feasible at nevirapine modified carbon paste electrode, the detection limit of paracetamol and folic acid were found to be 0.77μM, 2.53μM respectively. The practical utility of the proposed electrode was evaluated by analysing paracetamol in pharmaceutical sample with satisfactory result.
