“…Assim, dentre os metais estudados, o xerogel apresenta maior afinidade para adsorção de Cr(III). A maior capacidade de adsorção, bem como a cinética mais favorável para os íons Cr(III), pode ser justificada considerando-se a 31 .…”

“…The primary grafting reaction has been well studied [1][2][3][4]. This technique involves the immobilization of the organic group using an organosilane as a coupling reagent [5][6][7]. The resulting solids present a strong covalent bonded organic phase [7].…”

“…12 It has been observed that the degree of adhesion of the metal oxide layers depends on the degree of dispersion of the hydrated metal oxide and its thickness on the cellulose surface. [13][14][15][16] Among the metal oxides, Nb 2 O 5 coated solid substrate surfaces have merited considerable attention, in view of the local structure of the oxide particles, [17][18][19][20] its properties and potential applications. 21 Furthermore, the additional adsorption of phosphoric acid on a surface containing the oxide can considerably increase the surface acidity, which may be useful in heterogeneous catalytic reactions and in ion exchange.…”
