dc.description.abstract | For first time the complexation of bentazon (Btz) with native β-cyclodextrin (β-CD) and modified sulfobutylether-β-CD (SBE-CD) was studied by differential pulse voltammetry. In addition, a spectrophotometry UV-Visible study was carried out. In presence of CDs there is a decrease of the anodic peak current with the increase of the amount of CD. This decrease is due to the lower diffusion coefficient of Btz/CD complex compared with the free guest. Using the variation in current, association constants of 118± 20 and 317 ± 25 M-1 for β-CD and SBE-CD were determined. The solubility of bentazon was 8 fold higher with SBE-CD as compared with bentazon-free. Phase solubility diagrams performed using UV-Vis experiments permit to obtain the same association constants which were compared with the values obtained by electrochemical techniques. © 2010 Springer Science+Business Media B.V. | |
