Several techniques have been proposed for treatment of spectrophotometric data, with the objective of extracting a largest amount of analytical information from spectra composed of unresolved bands. Undoubtedly, a major success was achieved by derivative treatment of the absorbance curves-plotting of the first or a higher order mathematical derivative of absorbance against wavelength (dA/d lambda). Derivative spectrophotometry has been applied to many chemical systems. such as pharmaceuticals, foods, cosmetics, and environmental samples. The instrumental development and analytical applications of derivative UV-vis regions absorption spectro photometry produced in the last 5 years (since 2004) are reviewed. (c) 2008 Elsevier B.V.
