| Abstract | dc.description.abstract | For first time the complexation of bentazon (Btz)
with native b-cyclodextrin (b-CD) and modified sulfobutylether-
b-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 b-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. | en_US |
