Simultaneous sequential determination of compounds of toxicological interest in mixtures by derivative spectroscopy.
An absorption spectroscopic method was developed for the sequential determination of mixture components. The proposed method is straightforward and convenient and provides optimal results that increase the potential of spectrophotometric techniques as applied to date. The method was applied to the sequential resolution of mixtures of pure components of toxicological interest yielding close UV absorption bands by using derivative spectroscopy.
