This review summarizes and discusses the preparation and the application of emulsified systems in preparing samples prior to the analytical determination of metals by spectrometric methods. We present and discuss the experimental parameters, such as the choice of surfactant, emulsion-preparation mode and the influences on emulsification processes. We comprehensively summarize published studies covering the application of emulsification as a sample-preparation procedure for the analysis of food, cosmetics and petroleum-based samples. We also describe the main analytical techniques used for the determination of metals by spectrometric methods.
