Construction of novel NH2-Al-SBA-15 based mesoporous molecular sieve and application in the adsorption of methylene blue
Methylene blue is one of the most common compounds in mutagenic, teratogenic and carcinogenic dye wastewater. Adsorption is a simple and effective method for efficient treatment of organic wastewater. In this study, amine functionalized Al-SBA-15 mesoporous molecular sieves were prepared for adsorption of methylene blue solution. Solid waste fly ash was utilized as a cheap source of silica, which was combined with templating agent P123 to form Al-SBA-15 molecular sieves. Then silane coupling agent (APTES) was used to graft amine groups on the surface of Al-SBA-15 to improve the adsorption performance. The adsorption experiments showed that NH2-Al-SBA-15 had the best adsorption performance, with 324 mg g−1 against 200 mg L−1 methylene blue solution in 500 min. But the adsorption of Al-SBA-15 was 311 mg g−1. It proved that the functionalization increased the adsorption of methylene blue by the molecular sieve. Then the kinetic study was carried out, which showed that it conformed to the proposed secondary kinetics as well as Langmuir isothermal adsorption model. Then the effects of pH, adsorption temperature and methylene blue concentration on the adsorption performance were investigated. The optimal adsorption performance was obtained, and it resulted in the optimal adsorption pH value of 10, adsorption temperature of 25 °C, methylene blue concentration of 200 mg L−1, and mass of adsorbent of 30 mg.
期刊介绍：
The Journal of Porous Materials is an interdisciplinary and international periodical devoted to all types of porous materials. Its aim is the rapid publication
of high quality, peer-reviewed papers focused on the synthesis, processing, characterization and property evaluation of all porous materials. The objective is to
establish a unique journal that will serve as a principal means of communication for the growing interdisciplinary field of porous materials.
Porous materials include microporous materials with 50 nm pores.
Examples of microporous materials are natural and synthetic molecular sieves, cationic and anionic clays, pillared clays, tobermorites, pillared Zr and Ti
phosphates, spherosilicates, carbons, porous polymers, xerogels, etc. Mesoporous materials include synthetic molecular sieves, xerogels, aerogels, glasses, glass
ceramics, porous polymers, etc.; while macroporous materials include ceramics, glass ceramics, porous polymers, aerogels, cement, etc. The porous materials
can be crystalline, semicrystalline or noncrystalline, or combinations thereof. They can also be either organic, inorganic, or their composites. The overall
objective of the journal is the establishment of one main forum covering the basic and applied aspects of all porous materials.
