Resumo: | ABSTRACT: This work presents theory and applications in capillary electrophoresis. This technique is a powerful tool representing a large saving in chemicals (0.5 to 4 nL s-1 flux), samples (1 to 100 nL), and method development time. In addition, this work pictures applications such as separation and determination of analytical compounds. Recent reviews were cited to provide essential information for users regarding data sources, pioneer works, and theoretical treatments. The technique is reliable to study air, soil, and water samples in order to be able to determine trace amounts of pollutants. Examples of trace elements, pesticides, and humic substances analyses were showed. Separation and determination of proteins, peptides, aminoacids, nucleic acids, whole cells, transition metal complexes, metal oxiacids, surfactants, fenols, alifatic amines, sulfonic aromatic acids, dyes, plant nutrients and explosives are also possible.
