Abstract

Magnesium oxide and its composites with Fe₂O₃ or SiO₂ particles were prepared by an aerogel method for the removal of 2-chloroethyl ethyl sulfide (2-CEES) under ambient condition. Their sorption capacity and reactivity were evaluated by breakthrough experiments using 2-CEES of 0.26μg/mL in N₂ flow. The surface area and sorption capacity of aerogel MgO (AP-MgO) were about five times greater than those of commercial MgO. All of the prepared materials could decompose 2-CEES at 25°C with different conversion degrees. The reactivity of MgO·Fe₂O₃ composites was higher than that of AP-MgO and MgO·SiO₂. On the other hand, the increased surface area, imparted by the addition of SiO₂, led to the enhanced sorption capacity (49.3mg/g). The order of sorption capacity was MgO·SiO₂ > AP-MgO > MgO·Fe₂O₃, but the order of reactivity was MgO·Fe₂O₃ > AP-MgO > MgO·SiO₂.
