“…It is reported that when the HNT content increases, the peak intensity of the −OH increases owing to the Al–OH groups on the inner surface of HNT. 70 The peak intensities at 1625 and 3409 cm –1 decrease more in the spectrum of PAN-HNT-0.5 compared to those of other membranes. This can be attributed to the good dispersion of HNT in the PAN-HNT-0.5 membrane, as observed in the TGA and SEM characterizations.…”

This research focuses on the production and characterization of pristine polyacrylonitrile (PAN) as well as halloysite nanotube (HNT)-doped PAN ultrafiltration (UF) membranes via the phase inversion technique. Membranes containing 0.1, 0.5, and 1% wt HNT in 16% wt PAN are fabricated, and their chemical compositions are examined using Fourier transform infrared (FTIR) spectroscopy. Scanning electron microscopy (SEM) is utilized to characterize the membranes’ surface and cross-sectional morphologies. Atomic force microscopy (AFM) is employed to assess the roughness of the PAN/HNT membrane. Thermal characterization is conducted using thermal gravimetric analysis (TGA) and differential thermal analysis (DTA), while contact angle and water content measurements reveal the hydrophilic/hydrophobic properties. The pure water flux (PWF) performance of the porous UF water filtration membranes is evaluated at 3 bar, with porosity and mean pore size calculations. The iron (Fe), manganese (Mn), and total organic carbon (TOC) removal efficiencies of PAN/HNT membranes from dam water are examined, and the surfaces of fouled membranes are investigated by using SEM post-treatment. Mechanical characterization encompasses tensile testing, the Mori–Tanaka homogenization approach, and finite element analysis. The findings offer valuable insights into the impact of HNT doping on PAN membrane characteristics and performance, which will inform future membrane development initiatives.

“…Because of the presence of amino groups, this material may be employed immediately in solid form for adsorption applications (complexation of cations or organic molecules, electrostatic attraction or ion exchange in acidic media) . It may also be employed in liquid form (dissolved in acidic media) to neutralize charges, coagulate-flocculate anionic species (dissolved materials, colloids, and suspended particles), and complex metal ions …”

Pervaporation is regarded as one of the most promising technologies for desalination due to its extremely low energy consumption and ability to process high salinity solutions. As an easily accessible natural material with various advantages, chitosan is a promising material for pervaporative desalination. However, the research in this regard is scarce, and all existing works only focus on the desalination of NaCl solutions. Since chitosan has the potential to chelate with various ions, its desalination performance for different salt solutions might vary. In this study, we applied chitosan‐based membranes to pervaporative desalination for various salt solutions. The effects that feed salts, feed concentration, and temperatures had on their performance were comprehensively investigated. Moreover, two types of chitosan (Chitosan‐K and Chitosan‐D) were utilized to investigate the impact of chitosan types and confirm the universality of the conclusion. It was found that the feed salts significantly impact the desalination performance of chitosan membrane depending on their chelation level with chitosan polymers, and the cations (rather than anions) of the salts have a more significant effect. The salt rejection was almost complete at all tested conditions, demonstrating chitosan to be a promising material for pervaporative desalination.
