“…The flux was found to be decreased with the increase in feed salinity, similar to other reports of seawater desalination through pervaporation 35 and membrane distillation. 36,37 Therefore, the higher E j value for the membrane process with the increase in salinity of the feed is due to the decrease in the water vapor pressure of the feed.…”

Pervaporation membrane technology is commercially successful in the dehydration of organic solvents, and the technology has potential for seawater desalination with high recovery because of its capability to treat highly saline water. But to make the technology advantageous over the other available membrane desalination technologies in terms of productivity flux without additional energy cost, the selective barrier layer is required to be extremely thin, defect‐free, hydrophilic, and selective to water. In this work, we prepared an efficient membrane by reinforcing a highly water‐permeable but continuous barrier layer of poly(vinyl alcohol)–silica (PVA‐SiO2) hybrid material on porous polysulfone hollow fibers. The PVA‐SiO2 in acidified and hydrated ethanol was aged at room temperature for a period to allow solvent evaporation to obtain the solution concentration desired for the reinforcement. The reinforced hollow fiber membrane with optimal PVA‐SiO2 barrier layer thickness exhibited a performance with a flux of 20.6 L m−2 h−1 and 99.9% salt rejection from a saline feed of 2000 ppm NaCl at 333 K. The effects of PVA‐SiO2, temperature, and feed salinity on the pervaporation performance of the membrane were also studied. © 2017 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2018, 135, 45718.

“…5,6 In comparison with organic polymer membranes, the inorganic membranes are more stable under harsh separation condition. So far, various inorganic membranes, such as carbon membrane, 7,8 zeolite membranes, [9][10][11] and metal organic frameworks membrane 12 have been developed for seawater desalination. Despite much progress in the development of membranes for seawater desalination, it is still highly desired to develop a novel membrane with high stability and high ions rejection for seawater desalination.…”

Nanohybrid graphene oxide (GO)/polyimide (PI) mixed matrix membranes (MMMs) were prepared by dispersing GO into PI through wet phase inversion method. The structure of GO/PI MMMs was characterized by using XRD, FT-IR and XPS. FESEM was used to analyze the morphology of the GO/PI MMMs. The hydrophilicity of the GO/PI MMMs was determined by static water contact angles. The performances of the GO/PI MMMs were evaluated for desalination of seawater through pervaporation.The GO/PI MMMs display excellent water permeability and salt rejection for desalination of different concentrations of seawater. At 90 C, the GO/PI MMMs exhibit a high water flux (36.1 kg m À2 h À1) and a high salt rejection (99.9%). Further, the GO/PI MMM displays a high stability for seawater desalination.This high separation performance combined with high stability and facile fabrication route recommend the developed GO/PI MMMs as a promising candidate for desalination of seawater.

“…Use of natural adsorbents has attracted considerable economical interest, since their estimated cost of production, milling, and sieving are less than that of synthetic ones [11][12][13][14][15][16]. Due to the widespread use of highly porous bodies and materials in the industry as sorbents, catalysts, fillers, etc.…”

A B S T R A C TZeolite, a well-known inorganic compound, was used for Pb(II) and Cd(II) sorption. For this purpose, the model system composed with "H 3 PO 4 -Pb 2+ -Cd 2+ " medium was selected and applied with various amounts of both heavy metal salts. The results revealed that sorption capacity of the sorbent was higher for Pb 2+ cation than in the diluted phosphoric acid (20% H 3 PO 4 ) for all periods. The absorption of toxic metal ions was measured by atomic absorption spectroscopy. Different physical and chemical analysis techniques such as Fourier Transform infrared, scanning electron microscope, DTA, and XRD showed that natural state of zeolite in a diluted phosphoric acid (20% H 3 PO 4 ) system underwent protonation and hydroxylation to produce additional OH − groups that are active in the sorption process and no destruction was observed in the structure.
