Modified screen-printed Electrode as Electrochemical Detector for Noscapine

摘要

In the present study, a La3+doped Co3O4 nanoflowers modified graphite screen-printed electrode(La3+doped Co3O4 nanoflower/SPE) were prepared and used for voltammetric determination ofnoscapine. Presence nanoflowers lead to a substantial improvement in current in compare to anunmodified electrode. The diagnostic methods used for the purposes of the study includechronoamperometry, differential pulse voltammetry (DPV) and cyclic voltammetry (CV) approaches.The modified SPE was used to determine noscapine in the range of 0.3 to 600.0 μM (LOD= 0.1 μM).
