Preparação de membranas de acetato de celulose organomodificadas para adsorção dos íons Cu(II), Cd(II), Mn(II) e Ni(II)

Abstract: . Cellulose acetate polymeric membranes had been prepared by a procedure of two steps, combining the method of phase inversion and the technique of hydrolysis-deposition. The first step was the preparation of the membrane, and together was organomodified with tetraethylortosilicate and 3-aminopropyltrietoxysilane. Parameters that exert influence in the complexation of the metallic ion, as pH, time of complexation, metal concentration, had been studied in laboratory using tests of metal removal. The membranes h… Show more

“…Thus, it is desirable monitoring and to develop analytical methodologies to detect and control the presence of this pharmaceutical in very different kinds of samples, from urine, serum or plasma and waste water, in which most of them having very complex matrices. [34][35][36][37][38] Cigarette filters (CFs) are alternative materials from cellulose acetate with great potential for adsorption and preconcentration of different analytes of several matrices, wildly used in separation area. 12 Conducting polymers and their composites have been extensively studied due to their interesting chemical and physical properties, in addition to their wide range of potential application, such assensors, 13 thermoelectric, 14 electrodes, 15 supercapacitors 16 etc.…”

“…Pode-se encontrar na literatura trabalhos sobre a capacidade adsortiva da resina Amberlite XAD ® -2, da quitosana e dos polímeros acetato de celulose e polisulfona. Goveia et al (2010), em seu trabalho com membranas de acetato de celulose, mencionaram que a remoção (BOUSHER et al, 2007;WANG & XING, 2007). Com relação ao processo de purificação de biodiesel, Squissato et al (2015) relataram a eficiência de um material celulósico (celulose de eucalipto) na remoção de glicerol livre presente em uma amostra de biodiesel.…”
