Synthesis and evaluation of new organofunctionalized silica materials obtained by sol-gel methods applied to ethinylestradiol adsorption
Abstract The presence of micropollutants in the environment has been detected in a number of springs in Brazil and in several other countries. Despite the low concentrations of these compounds in aquatic environments, they are capable of causing biological effects on aquatic organisms. Thus, new met...

| 520 | |a Abstract The presence of micropollutants in the environment has been detected in a number of springs in Brazil and in several other countries. Despite the low concentrations of these compounds in aquatic environments, they are capable of causing biological effects on aquatic organisms. Thus, new methods for removing these contaminants need to be pursued. This work reports the synthesis and characterization of a xerogel based on an inorganic core of rigid silica obtained by the sol-gel method, and four adsorbents were synthesized from the organofunctionalization of a silica network, with the ligands cyclohexylamine (CyA), aniline (PhA), benzylamine (BnA) and 2-picolylamine (AMPy), which showed high potential for application as an adsorbent for the emerging contaminant ethinylestradiol. The materials were characterized using IR, 13C and 29Si NMR, CHN, TGA, SEM, and BET techniques, which show that adsorbents were formed and that they are particulate, non-porous, and thermally stable up to approximately 548 K. Adsorbent properties were studied, observing the optimum pH value of 5.5 and the equilibrium time in 60 minutes. The experimental data for the adsorption isotherms were closely modeled on the Langmuir and Freundlich models, as a spontaneous process that fits both models and showing adsorption capacity values between 1.05 and 1.46 mmol $ g^{−1} $. The regeneration conditions with acetonitrile were tested; reuse was studied for six cycles and showed very satisfactory results. Graphical abstract | ||

Despite the low concentrations of these compounds in aquatic environments, they are capable of causing biological effects on aquatic organisms. Thus, new methods for removing these contaminants need to be pursued. This work reports the synthesis and characterization of a xerogel based on an inorganic core of rigid silica obtained by the sol-gel method, and four adsorbents were synthesized from the organofunctionalization of a silica network, with the ligands cyclohexylamine (CyA), aniline (PhA), benzylamine (BnA) and 2-picolylamine (AMPy), which showed high potential for application as an adsorbent for the emerging contaminant ethinylestradiol. The materials were characterized using IR, 13C and 29Si NMR, CHN, TGA, SEM, and BET techniques, which show that adsorbents were formed and that they are particulate, non-porous, and thermally stable up to approximately 548 K. Adsorbent properties were studied, observing the optimum pH value of 5.5 and the equilibrium time in 60 minutes. The experimental data for the adsorption isotherms were closely modeled on the Langmuir and Freundlich models, as a spontaneous process that fits both models and showing adsorption capacity values between 1.05 and 1.46 mmol $ g^{−1} $. The regeneration conditions with acetonitrile were tested; reuse was studied for six cycles and showed very satisfactory results.

Despite the low concentrations of these compounds in aquatic environments, they are capable of causing biological effects on aquatic organisms. Thus, new methods for removing these contaminants need to be pursued. This work reports the synthesis and characterization of a xerogel based on an inorganic core of rigid silica obtained by the sol-gel method, and four adsorbents were synthesized from the organofunctionalization of a silica network, with the ligands cyclohexylamine (CyA), aniline (PhA), benzylamine (BnA) and 2-picolylamine (AMPy), which showed high potential for application as an adsorbent for the emerging contaminant ethinylestradiol. The materials were characterized using IR, 13C and 29Si NMR, CHN, TGA, SEM, and BET techniques, which show that adsorbents were formed and that they are particulate, non-porous, and thermally stable up to approximately 548 K. Adsorbent properties were studied, observing the optimum pH value of 5.5 and the equilibrium time in 60 minutes. The experimental data for the adsorption isotherms were closely modeled on the Langmuir and Freundlich models, as a spontaneous process that fits both models and showing adsorption capacity values between 1.05 and 1.46 mmol $ g^{−1} $. The regeneration conditions with acetonitrile were tested; reuse was studied for six cycles and showed very satisfactory results.

Synthesis and evaluation of new organofunctionalized silica materials obtained by sol-gel methods applied to ethinylestradiol adsorption |
| abstract |
Abstract The presence of micropollutants in the environment has been detected in a number of springs in Brazil and in several other countries. Despite the low concentrations of these compounds in aquatic environments, they are capable of causing biological effects on aquatic organisms. Thus, new methods for removing these contaminants need to be pursued. This work reports the synthesis and characterization of a xerogel based on an inorganic core of rigid silica obtained by the sol-gel method, and four adsorbents were synthesized from the organofunctionalization of a silica network, with the ligands cyclohexylamine (CyA), aniline (PhA), benzylamine (BnA) and 2-picolylamine (AMPy), which showed high potential for application as an adsorbent for the emerging contaminant ethinylestradiol. The materials were characterized using IR, 13C and 29Si NMR, CHN, TGA, SEM, and BET techniques, which show that adsorbents were formed and that they are particulate, non-porous, and thermally stable up to approximately 548 K. Adsorbent properties were studied, observing the optimum pH value of 5.5 and the equilibrium time in 60 minutes. The experimental data for the adsorption isotherms were closely modeled on the Langmuir and Freundlich models, as a spontaneous process that fits both models and showing adsorption capacity values between 1.05 and 1.46 mmol $ g^{−1} $. The regeneration conditions with acetonitrile were tested; reuse was studied for six cycles and showed very satisfactory results. Graphical abstract Highlights A simple and easily obtainable method for silica matrices is described.Xerogel organofunctionalization follows a simple route for development of adsorbents.The final matrices show high adsorption capacity of the contaminant ethinylestradiol.Adsorbents showed high regeneration and reusability over 6 cycles. © The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2022 |
