Keywords:
sol-gel, mesoporous sorbent, diffractometry, specific surface area, pore volume
Abstract
A mesoporous Al2O3 sorbent was synthesized using sol-gel technology. The sorbent's phase composition was analyzed via X-ray diffractometry (XRD), while its surface morphology was studied using scanning electron microscopy methods. Textural characteristics were also investigated through the adsorption of toluene vapors on the sorbents with the help of Mak-Ben-Bakra's sensitive quartz spiral device. The specific surface area (SBET) of sorbents obtained at different temperatures was found to be 684,6 ± 10 m2/g, with a volume of pores (Vs) of 0,56 to 0,82 cm3/g and an average pore diameter of 12,4 ± 0,05 nm. X-ray microanalysis of the sorbents confirmed that their chemical composition corresponds to - Al2O3.
