“…Tel. : +55 liquid-liquid solvent extraction [4][5][6][7][8][9]. Although the utilization of polyurethane foams in separation and/or preconcentration procedures has increased since the pioneering work of Bowen, only few research works report a full characterization of the adsorption process of organic and/or inorganic substances onto unloaded and/or loaded PUF [10][11][12][13][14].…”

“…Alguns autores sustentam que as espumas de poliuretano podem atuar como extratores sólidos poliméricos, em um processo similar a uma extração líquido-líquido. [14][15][16][17] Alguns artigos podem ser encontrados na literatura descrevendo o uso de EPU como fase sólida para a extração de diferentes substâncias orgânicas em meio aquoso. [17][18][19][20][21] O objetivo deste trabalho foi avaliar a possibilidade de utilização das espumas de poliuretano como fase sólida para a retenção do corante catiônico violeta cristal em meio aquoso.…”

“…Most of them make use of chromatographic techniques; [1][2][3][4][5][6] others, in a lesser quantity, use spectrophotometry, [7][8][9][10] and fluorometry 11 and some biosensors have also been developed. [12][13][14][15] Simultaneous determinations of carbaryl and its hydrolysis product, 1-naphthol, have been reported by employing different methodologies.…”
