“…The isotherm for the MCM-41 sample exhibited H4 type hysteresis, corresponding to porous materials made up of narrow, slit-shaped pores. For SBA-15, the isotherm showed hysteresis of type H1 [23,51] associated with porous materials that consist of agglomerates or compact groups of uniform spheres in a regular arrangement and, therefore, have narrow pore size distributions.…”

“…This study is part of a line of research developed at the Laboratory for the Development of New Materials-LABNOV at UFCG. This line of research covered a series of studies on the synthesis and characterization of molecular sieves through different processes [21][22][23][24][25][26][27][28][29][30][31][32][33][34][35]. This study aims to reuse the mother liquor in three subsequent syntheses of the SBA-15 and MCM-41 molecular sieves to assess any possible changes in the physical, chemical, and morphological properties of each material.…”

The synthesis of mesoporous materials such as MCM-41 and SBA-15 requires large amounts of water to neutralize the resulting products. The ltrate (mother liquor) therefore contains unreacted components that can be recycled and reused. The addition of the mother liquor in consecutive syntheses was carried out in order to evaluate the different effects on the physical and chemical properties of the mesoporous materials. For this purpose, the mother liquor from the initial synthesis (1st Generation) was saved and used for the second synthesis (2nd Generation) and successively for the third synthesis (3rd Generation).The three generations of each material were then characterized using different techniques such as X-ray diffraction, X-ray dispersive energy uorescence, electron microscopy, infrared spectroscopy, Thermal behavior by thermogravimetric analysis and N 2 adsorption. The materials obtained showed similar diffractograms for the three generations and also showed similar percentages of silica through XRF. The SEM and IR results for molecular sieves showed the effectiveness of the processes of MCM-41 and SBA-15 synthesis using mother liquor. The results made it possible to observe that the structures of the materials had no signi cant differences in their physical and chemical properties, favoring the use of mother liquor for up to three generations.

Rhodamine (RhB) adsorption was carried out on MCM-41 and MCM-41 calcined. The effect of parameters such as pH was investigated. The reusability potential of MCM-41 was also established and the mechanism of RhB adsorption was discussed. MCM-41 was synthesized and calcined, with all samples characterized by X-Ray Diffractometry, X-ray Fluorescence by Dispersive Energy, Infrared Spectroscopy, Scanning Electron Microscopy, and Thermogravimetric analysis. The results of the characterization techniques performed confirmed the formation of the MCM-41 structure. During the adsorption of the RhB dye, high removal percentages and rapid kinetics occur in an acid medium. The adsorption kinetics was evaluated by two models: pseudo-first order and pseudo-second order. The pseudo-first-order kinetic model represented the interaction mechanism well during RhB adsorption by MCM-41. However, the pseudo-second-order model better represented the interaction mechanism during RhB adsorption by MCM-41 calcined. The regeneration study found that the MCM-41 and MCM-41 calcined were maintained at 80 and 90% of their original condition after three successive regeneration cycles. The overall results show that the process could be used as a strategy for environmentally sustainable wastewater treatment.
