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.

The application of porous aerogels for dye adsorption has proven to be an effective approach in wastewater treatment. In this study, bio-cellulose aerogels from coconut fibrils were successfully developed via the formation of physically cross-linking cellulose with non-toxic binders (polyvinyl alcohol (PVA) and xanthan gum (XTG)) resulting from a freeze-drying technique. The flexible aerogel composites demonstrated remarkably low density (27.59–47.76 g/cm3), high porosity (> 96.0%), compressive Young’s modulus (3.82–12.66 kPa), a specific surface area of 518.01 m2/g, and a desorption average pore diameter distribution of 3.77 nm. These aerogels were tested for crystal violet (CV) and methyl orange (MO) adsorption to evaluate their effectiveness in treating dye-polluted water via various conditions such as contact time, pH values, initial concentrations, and temperature. The dye adsorption process reached equilibrium after approx. 30 min and strictly followed pseudo-second-order and the Redlich-Peterson model. FT-IR and SEM-EDX analyses proved that the adsorption mechanism is primarily ascribed to the hydrogen bonding, electrostatic, π-π, and Vander Waals interactions between aerogel and dye molecules. The eco-friendly synthesis of recycled cellulose aerogels from coconut fibrils using green chemicals holds great promise for dye elimination.
