摘要

本研究旨在评估介孔二氧化硅MCM-41和Al-MCM-41（摩尔比Si/Al=20）从水溶液中去除罗丹明6G（Rh6G）的潜力。通过XRD、FTIR、SEM-EDX、BET和UV-Raman对吸附剂进行了表征。所获得的与XRD分析相关的结果表明，在引入Al物种后，MCM-41结构保持完整。动力学吸附研究表明，Al-MCM-41在60min时对Rh6G染料的去除率较高（88.75%，26.62mg g−1）。FTIR分析表明，氢键在Rh6G去除机理中起主导作用，而pH值结果表明，静电相互作用也是一个关键因素。本研究表明，制备的介孔材料是一种廉价高效的阳离子染料吸附剂。

Adsorption of Rhodamine 6G Dye onto Al-MCM-41 and MCM-41 Mesoporous Materials

The present study aimed to evaluate the potential of mesoporous silica MCM-41 and Al-MCM-41 (molar ratio Si/Al = 20) for the removal of Rhodamine 6G (Rh6G) from aqueous solution. The adsorbents were characterised by XRD, FTIR, SEM-EDX, BET, and UV-Raman. Obtained results related to XRD analysis indicated that the MCM-41 structure remained intact after the incorporation of Al species. Kinetic adsorption study showed that the higher removal (88.75 %, 26.62 mg g −1 ) of Rh6G dye was achieved by Al-MCM-41 at 60 min. FTIR analysis showed that hydrogen bonding played the dominant role in the Rh6G removal mechanism, while the pH results showed that electrostatic interaction was also a key factor. This study shows that the prepared mesoporous materials are inexpensive and efficient adsorbents for the removal of cationic dyes.
