| 초록 |
Amid continuously increasing environmental problems, the solution to these problems is being studied thoroughly. Eventually, volatile organic compounds(VOCs) can cause serious diseases, such as cancer, loss of sight, unconsciousness, etc. Therefore, many studies have been explored recently. Among the studies, the adsorption study has drawn plenty of attention due to the easy and economical process and high removal performance. However, there is still a desire to develop a high-performance adsorbent. In this study, VOC adsorbents were prepared through hydrothermal synthesis(Al-MWW) and some post-treatments(Al-delMWW, Ni-MWW, Ni-delMWW, and Ni-BEA), while their VOC adsorption performances, which were separated into total and chemisorbed amounts, were evaluated, depending on the type of adsorbates(BTX). Synthesized adsorbents were characterized via powder XRD, N2 sorption, IR spectroscopy, STEM-EDS, and ICP elemental analysis. |
