COMPOSTOS ORGÂNICOS E INORGÂNICOS CONTENDO SELÊNIO: REVISÃO DE MÉTODOS ANALÍTICOS E PERSPECTIVAS PARA ANÁLISES QUÍMICAS

[摘要] This article critically reviews the spectrometric, chromatographic and electroanalytical methods applied for the identification and quantification of organic and inorganic compounds containing Se and their applications in food, biological and natural water samples. The main characteristics, advantages and disadvantages of each analytical method are presented, and special attention is paid to sample preparation strategies prior to identification and quantification. Perspectives of research on new analytical procedures with improved speed, sensitivity, selectivity, accuracy, and mainly environmentally friendly, are also reported.
