Recent applications in derivative ultraviolet/visible absorption spectrophotometry: 2009-2011 A review

Derivative spectrophotometry (DS) has been introduced for the resolution of overlapping peaks. DS method has been widely used to enhance the signal and resolve the overlapped peak-signals due to its advantages in differentiating closely adjacent peaks, and identifying weak peaks obscured by sharp peaks. In this work, the analytical applications of derivative UV/VIS region absorption spectrophotometry produced in the last 3 years (since 2009) are reviewed. (c) 2012 Elsevier B.V. All rights reserved.
