MgO-Modified Activated Carbon Fibers for Enhanced Adsorption of Toluene: Efficiency and Mechanism
To enhance the surface functionalities of activated carbon fiber (ACF), the impregnation and high-temperature calcination methods were utilized to effectively load magnesium oxide on ACF. Dynamic adsorption tests were carried out to examine the impact of different doping amounts and calcination temperatures with respect to the adsorption performance of MgO/ACF on toluene, and it was characterized by SEM, XRD, N2 ad-desorption isotherms and FT-IR technique. When Mg/ACF mass ratio was 3% and a calcination temperature of 550 °C, the Mg0.03/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-filling mechanisms.
期刊介绍：
The Korean Journal of Chemical Engineering provides a global forum for the dissemination of research in chemical engineering. The Journal publishes significant research results obtained in the Asia-Pacific region, and simultaneously introduces recent technical progress made in other areas of the world to this region. Submitted research papers must be of potential industrial significance and specifically concerned with chemical engineering. The editors will give preference to papers having a clearly stated practical scope and applicability in the areas of chemical engineering, and to those where new theoretical concepts are supported by new experimental details. The Journal also regularly publishes featured reviews on emerging and industrially important subjects of chemical engineering as well as selected papers presented at international conferences on the subjects.
