MgO-Modifi ed Activated Carbon Fibers for Enhanced Adsorption of Toluene: Efficiency and Mechanism
Abstract
To enhance the surface functionalities of activated carbon fi ber (ACF), the impregnation and high-temperature calcination
methods were utilized to eff ectively load magnesium oxide on ACF. Dynamic adsorption tests were carried out to examine
the impact of diff erent doping amounts and calcination temperatures with respect to the adsorption performance of MgO/
ACF on toluene, and it was characterized by SEM, XRD, N 2 ad-desorption isotherms and FT-IR technique. When Mg/ACF
mass ratio was 3% and a calcination temperature of 550 °C, the Mg 0.03 /ACF-550 composite material revealed the optimum
adsorption capacity of toluene was 230.8 mg/g, which was 31% higher than the original ACF, and it could be regenerated
and permitting reuse for multiple cycles. Its adsorption process of toluene occurred via a combination of surface adsorption
and pore-fi lling mechanisms.
