摘要:
The influence of cyclodextrins on the electrochemical response of some pharmaceutical molecules has been investigated on carbon paste electrode (CPE) using cyclic voltammetry (CV) and square wave voltammetry (SWV). The oxidation peak of the analytes is shifted to internal positive potential values and the current intensity is decreased, modifications which can be explained by the formation of inclusion complexes. FUR studies were used to confirm the complexation. Carbon paste electrodes modified with beta-cyclodextrin (CPE/ beta-CD) showed an enhanced electrochemical response of ascorbic and uric acid in comparison with the unmodified carbon paste electrode.
