چکیده
|
In this research we describe application of ficus carica sub sp. rupestris for biosynthesis of ag nanoparticle in the first step. the synthesized nanoparticle was characterized by tem and uv-vis spectroscopy methods. in the continuous a carbon paste electrode modified with ag nanoparticle (cpe/m/ag/nps) was fabricated as a highly sensitive sensor for ascorbic acid analysis. the cpe/m/ag/nps showed good catalytic activity for electrochemical analysis of ascorbic acid using voltammetric methods. the anodic peak current was linearly proportional to the concentration of ascorbic acid in the range from 0.09 to 600.0 µm with detection limit of 0.02 µm. the cpe/m/ag/nps was successfully applied to ascorbic acid determination in food and pharmaceuticals samples. © 2017 by cee (center of excellence in electrochemistry).
