In situ fabrication of hierarchical biomass carbon-supported Cu@CuO–Al2O3 composite materials: synthesis, properties and adsorption applications

“…In the present work, the adsorption isotherm models of NH 4 + -N on the as-prepared adsorbents were tested with three adsorption isotherm models: the Langmuir, Freundlich and Temkin models. The mathematical adsorption equations are expressed as follows: 18 Langmuir…”

Efecto de la adición de bentonita sobre las propiedades ópticas de diferentes materiales compuestos poliméricos

“…En las Figuras 1c y 1d se observa que ambos minerales presentan una morfología típica de las arcillas conformadas por una estructura laminar en escamas [20]. Otros autores han reportado morfologías similares para diferentes partículas minerales [21,22]. La superficie de las partículas presentan poros, intersticios y cavidades.…”
