“…The organic extractants 0.75 M D2EHPA and 0.75 M TBP diluted in kerosene were loaded into the pores of the hollow fiber contactor in the similar manner as described in our earlier work. [30][31] The HFLSM experiments were operated in recycling mode. The schematic of the HFSLM set-up can be found elsewhere.…”

Extraction of Lithium (Li + ) from synthetically prepared sea bittern using di-2-ethyl hexyl phosphoric acid (D2EHPA) and tri-n-butyl phosphate (TBP) as organic extractants has been studied. The equilibrium studies conducted shows synergistic effect between D2EHPA and TBP. The equilibrium constant values for Li + , Na + and K + ions were found to be 95.4×10 -5 m 3 /kmol, 4.6×10 -5 m 3 /kmol and 3.69×10 -5 m 3 /kmol respectively. Hollow fiber supported liquid membrane experiments with low concentration of Li + , Na + and K + ions in feed phase, showed Downloaded by [University of Birmingham] at 02:28 25 June 2016A c c e p t e d M a n u s c r i p t 1 high flux for Li + ions. However at significantly high concentrations of Na + and K + in feed phase, the flux of Li + ions reduced. The model predictions were found in good agreement with the experimental data.

“…Nowadays, because of its outstanding advantages that new substances are not introduced during the separation process with no secondary pollution, the pervaporation technology − has become one of the most preferable separation processes. Because of its energy saving nature, easy operation, and requires simple equipment, pervaporation is a promising method for the recovery of pyridine from a low-concentration pyridine solution. − Singha et al used carbon black (N330 grade) to fill the styrene–butadiene rubber membrane that was used to remove pyridine, and the membrane exhibits better selectivity and mechanical strength. Ray et al studied the combination of sulfur-sulfurized RSS4 natural rubber and carbon black (N330 grade) to make a cross-linked membrane for pervaporation.…”

A two-dimensional molybdenum disulfide (MoS 2 ) nanosheet, as a new type of inorganic material with high hydrophobicity and excellent physicochemical stability, holds great application potential in the preparation of a high separation performance organic− inorganic hybrid membrane. In this work, high hydrophobic MoS 2 was embedded in hydrophobic polyether copolymer block amide (PEBA) to prepare PEBA/MoS 2 organic− inorganic hybrid membranes. The structure, morphology, and hydrophobicity of the hybrid membrane were characterized by scanning electron microscopy, thermogravimetric analysis, contact angle goniometry, X-ray diffraction, infrared spectroscopy analysis, and atomic force microscopy. The effect of embedding of MoS 2 on the swelling degree and pervaporation separation performance of the PEBA/MoS 2 hybrid membrane was studied with a 1.0 wt % pyridine dilute solution. The results indicated that with increasing the MoS 2 content, the separation factor of PEBA/MoS 2 increased first and then decreased, while it showed a downward trend in the permeation flux. When the MoS 2 content in the PEBA/MoS 2 hybrid membrane was 10.0 wt %, the permeation flux was 83.4 g m −2 h −1 (decreased by 21.5% compared with the pure PEBA membrane), and the separation factor reached a maximum value of 11.11 (increased by 37.6% compared with the pure PEBA membrane). Meanwhile, the effects of feed temperature on the pervaporation separation performance of PEBA/MoS 2 hybrid membranes were also studied. In addition, as the PEBA/MoS 2 hybrid membrane has excellent thermal stability, it is expected to be a promising material for recovering pyridine from wastewater.

“…Among the different organic pollutants in wastewater, pyridine behaves as an interesting pollutant. In fact, it is a basic heterocyclic organic compound [3], which persists for longer duration in water. It is widely used as a solvent and intermediate in the production of agricultural chemicals, drugs, dyestuffs and paints, rubber products, polycarbonate resins and textile water-repellents, as well as in laboratories [4].…”

Activated Montmorillonite was applied for the sorption of pyridine as a health-toxic substance. Fourier-transform Infrared spectroscopy (FTIR), zeta potential analysis, thermogravimetric analysis (TGA), N 2 physisorption analysis and X-ray diffraction (XRD) method were used to investigate the structure and composition of Montmorillonite. The batch sorption system was used to study the effect of different parameters on the adsorption. Results had shown that neutral pH had a significant effect on the sorption of pyridine; thermodynamic calculations indicated that the adsorption of pyridine over Montmorillonite was exothermic reaction and the equilibrium capacity was slightly increased by using H 2 SO 4 as activating agent by comparison with that obtained by using HCl and H 3 PO 4. Fitting the experimental data to isotherms models indicated that the experimental data were well fitted by Fowler Guggenheim isotherm models. Finally the results obtained by FTIR and TGA proved that the relative affinity of the pyridine toward the Montmorillonite was related to the electron donor-acceptor complexes that were formed between the basic sites (nitrogen or oxygen) and hydrogens (acidic site).
