Abstract

The theoretical evaluation for the use of
vanadium (III) oxyhydroxide as an electrode modifier for benzodiazepines’
electrochemical determination in acid solutions has been made. The
correspondent mathematical model has been developed and analyzed by means of the
linear stability theory and bifurcation analysis. It was shown that VO(OH) may
be an efficient electrode modifier for the benzodiazepines electrochemical
determination in lightly and moderately acid solution. Its use in concentrated
acidic solution may be compromised by modifier destruction. The oscillatory
behavior in this system may be caused not only by the DEL influences of the
electrochemical stage, but also by surface instabilities, caused by VO(OH)
dissolution.
