“…With respect to the release experiments, 10 mg of MOF was added to 20 mL of an aqueous solution of PPB (10 mg L −1 ) and, after 24 h, the sample was removed. Then, 5 mL of methanol was added and aliquots of the methanolic solution (50 μL) were taken at prefixed times (1,5,10,15,30,45,60,90,120,240,480, and 1440 min), filtered and injected in the UHPLC for the quantification of the PPB desorbed at each timing. The release in water was also carried out with 10 mg of adsorbent (CIM-81).…”

Metal−organic frameworks (MOFs) are attractive materials used as sorbents in analytical microextraction applications for contaminants of emerging concern (CECs) from environmental liquid matrices. The demanding specs for a sorbent in the analytical application can be comprehensively studied by considering the interactions of the target analytes with the frameworks by the use of single-crystal X-ray diffraction, computational analysis, and adsorption studies, including the kinetic ones. The current study intends a better understanding of the interactions of target CECs (particularly, propylparaben (PPB) as a model) and three Zn-based layered pillared MOFs: CIM-81 [Zn 2 (tz) 2 (bdc)] (Htz = 1,2,4triazole and H 2 bdc = 1,4-benzenedicarboxylic acid) and their amino derivatives [Zn 2 (NH 2 -tz) 2 (bdc)] CIM-82 and [Zn 2 (tz) 2 (NH 2 -bdc)] CIM-83 (NH 2 -Htz = 3-amino-1,2,4-triazole and NH 2 -H 2 bdc = 2-amino-1,4-benzenedicarboxylic acid).

“…In addition, increasing the molecular size of the substituent group often increases the adsorption capacity, especially for a homologous series of parabens. 16,60 Furthermore, these results offer powerful evidence supported by many authors who argued that the chemical and physical properties of cellulose required for remotion of pollutants depend on molecules worked 19,61,62 The isotherm parameters for the three isotherm models that worked with linear regression coefficient (R 2 ) and the sum of the squares of the error (SSE) are listed in Table S5. According to R 2 and SSE, both the Langmuir and the Sips adsorption models could satisfactorily describe the paraben adsorption on each modified cellulose, while the Freundlich isotherm model was the least suitable.…”

“…The XRD pattern of MC in Figure 5 shows the typical structure of cellulose I with peaks at 2θ = 15.40°and 22.40, which are characteristic of crystalline cellulose and correspond to the diffraction lattice planes of (110) and (020), and this is consistent with Van et 53 The processed MCM material showed signals at 2θ = 35.50, 57.34, and 63.00°, indicating the presence of Fe 3 O 4 and corresponding to the diffraction lattice planes of (311), (440), and (511) (JCPDS card 01-075-0449), and similar to the results of previous works. 54,55 In addition, due to the alkaline treatment of the MCM material, the crystalline peak of MC (22.40°) split into two peaks located at 2θ = 20.02 and 21.80°, showing a typical structure of cellulose II. A shift of the MC peak from 15.40 to 11.78°is also recorded in the MCM characteristic of cellulose II.…”

Emerging contaminants are chemical products that are found in low concentrations, are not regulated by environmental norms, and cause health effects. Among this group of contaminants are parabens, a family of p-hydroxybenzoic acid esters used as preservatives in cosmetics, pharmaceuticals, and food products. Recent research describes parabens as endocrine disruptors that can cause health alterations. Some of the best alternatives for pollutant removal include the adsorption process, which can use materials that are inexpensive, abundant, and susceptible to modifications. In this sense, cellulose can be an option for obtaining materials that can be used in the removal of contaminants. This research investigates the synthesis of benzoic cellulose (MCB) and magnetic cellulose (MCM) as well as its use as an adsorbent for the removal of methylparaben (MP) and butylparaben (BP) from water. Likewise, physicochemical characterization, including Fourier transform infrared (FTIR), scanning electronic microscopy (SEM), energy-dispersive spectroscopy (EDS), X-ray diffraction (XRD), and thermogravimetric analysis (TGA), for both cellulose materials was carried out. Moreover, pseudo-first-order, pseudo-second-order, Elovich, Weber, Morris, and Boyd models were used to investigate the adsorption kinetics. As a result, the pseudo-second-order model was favorable for both modified cellulose and the two parabens assayed. Finally, Freundlich, Langmuir, and Sips adsorption isotherm models were investigated; the Langmuir model was the best for the adsorption isotherm data. The adsorption of methylparaben and butylparaben was in the following order: MCM > MCB. The maximum adsorption capacity of MP and BP for MCM was 9.58 and 12.03 mg g −1 , respectively. For instance, the results showed that the modified cellulose adsorbed the parabens physically, which could involve electrostatic attraction, hydrogen bonding, π−π bonding, and hydrophobic interactions.

“…33 For these samples, the H3 type hysteresis loop (according to IUPAC classication) was observed, which was related to non-rigid aggregates of plate-like particles. 27,34,35 In addition, with the decreasing of Cu content, the condensation occurred at relatively low pressure. Fig.…”
