چکیده
Inclusão-separação e pre-concentração de dioxina em amostras de sangue são descritas pelo processo de emulsão de nano membrana líquida de inclusão-facilitada. A novidade deste estudo está na aplicação de nano-bastões de calixareno assim como membranas líquidas de emulsão na pre-concentração seletiva e eficiente da dioxina. Para este fim, parâmetros de extração-inclusão de quatro derivados de p-tert-calix[4]areno com sulfonamidas sintetizados previamente foram investigados. As análises por cromatografia gasosa revelaram que sob condições otimizadas de operação, a pre-concentração da dioxina foi melhorada e o método atingiu menores limites de detecção.
