Description
Summary:The use of surfactants to enhance spectrophotometric procedures for the determination of organic species is critically reviewed. Special emphasis is placed on the effects of surfactants on chromogenic derivatization reactions. The following topics are addressed: modification of acid-base and solubility equilibria, spectral changes, modification of reaction rates, and applications in equilibrium-and kinetic-based analytical procedures. Applications to flow injection procedures are also briefly reviewed.
