“…Because the organic functionalities are direct components of the silica matrix, pore blocking is not a problem with the onepot synthesis method. In addition, the organic functional compounds are more homogeneously distributed than with the post-synthesis process (Kao et al 2008). For this reason, the maximum adsorption capacity of one-pot synthesized MCM-41 exhibited a similar level to that of the post-synthesized MCM-41.…”

In the present study, the applications of mesoporous materials based on silica, namely postsynthesized, one-pot synthesized, and pure MCM-41, were investigated for the removal of phosphate from aqueous solution. The mesostructures were confirmed by X-ray diffraction, Brunauer-Emmett-Teller, Fourier transform spectroscopy, and transmission electron microscopy. The absorptions of phosphate by the mesoporous adsorbents were examined, with different adsorption models used to describe the equilibrium and kinetic data. The maximum adsorption capacities of the mesostructure adsorbents were found to be 45.162, 40.806, and 31.123 mg g -1 for the post-synthesized, one-pot synthesized, and pure MCM-41, respectively. The kinetic data showed that the adsorptions of phosphate onto the post-synthesized and pure MCM-41 followed the pseudo-first-order kinetic model, whereas the one-pot synthesized adsorbent was described by the pseudo-second-order model.

“…The -CH 2 -and -CF 2 -carbons of the PVDF main chains contribute to the peaks at 44.6 ppm and 121.8 ppm [29]. For the spectra (curves a and b), the peaks at 10.9, 21.9, and 50.3 ppm can be assigned to a and b carbons of -CH 2 -groups [30,31], and -OCH 3 group [32] of APTMS ((H 3 CO) 3 Si-CH 2 (a)-CH 2 (b)-CH 2 (c)-NH 2 ), respectively. The peak appearing at 59.1 ppm is assigned to -CH 2 N-carbon of DTPA and the peak at 169.8 ppm can be attributed to the carboxylic and acylamide groups of APTMS-DTPA compounds.…”

He (2015) Adsorption performance of APTMS-DTPA/PVDF chelating membrane toward Ni(II) with the presence of Ca(II), NH 4 + , lactic acid, and citric acid, Desalination and Water Treatment, 53:1, 158-170, A B S T R A C TThe 3-aminopropyltrimethoxysilane-diethylenetriaminepentaacetic acid/polyvinylidene fluoride (APTMS-DTPA/PVDF) chelating membrane was prepared to remove Ni(II) from the solutions. The adsorption performance of the membrane toward Ni(II) was investigated by the adsorption experiments and density functional theory (DFT) calculations, considering the existence of Ca(II), NH þ 4 , lactic acid, and citric acid. Ca(II) tended to form more stable complex with the APTMS-DTPA ligand of the chelating membrane than NH þ 4 . Citric acid showed a larger interference on Ni(II) uptake than lactic acid. Lagergren second-order equation and Langmuir model were competent for descriptions of the adsorption kinetics and the isotherms, respectively. The negative DG˚and DH˚indicated the spontaneous and exothermic nature of Ni(II) adsorption. The results of DFT calculations were consistent with the experimental data. The complexing sequences of the metal ions with the APTMS-DTPA ligand were in the order of NH þ 4 < Ca(II) < Ni(II). The stabilities of the Ni(II)-organic complexes followed the order of Ni(II)-lactic acid < Ni(II)-citric acid < Ni(II)-(APTMS-DTPA). Therefore, the complexation between Ni(II) and APTMS-DTPA ligand of the membrane was prominent.

Mesoporous silicas have enjoyed great interest among scientists practically from the moment of their discovery thanks to their unique attractive properties. Many types of mesoporous silicas have been described in literature, the most thoroughly MCM-41 and SBA-15 ones. The focus of this review are the methods of syntheses, characterization and use of mesoporous silicas from SBA (Santa Barbara Amorphous) and HMM (Hybrid Mesoporous Materials) groups. The first group is represented by (i) SBA-1 of three-dimensional cubic structure and Pm3n symmetry and (ii) SBA-2 of three-dimensional combined hexagonal and cubic structures and P63/mmc symmetry. The HMM group is represented by (i) HMM-1 of two-dimensional hexagonal structure and p6mm symmetry and (ii) HMM-2 of three-dimensional structure and P63/mmc symmetry. The paper provides comprehensive information on the above-mentioned silica materials available so far, also including the data for the silicas modified with metal ions or/and organic functional groups and examples of the materials applications.
