“…Rad et al . prepared a poly(vinyl alcohol)/zeolite nanofibrous adsorbent by electrospinning, and investigated its application for the removal of Ni 2+ and Cd 2+ ions from aqueous solutions . The adsorption results indicated that the prepared adsorbent showed a higher affinity for Cd 2+ than Ni 2+ with maximum adsorption capacity of 342.8 and 838.7 mg g −1 for Ni 2+ and Cd 2+ , respectively.…”

Nanofibers have unique functionalities based on their nanoscaled cross‐section, high specific surface area, and high molecular orientation inside the fibers. These functionalities can be improved by controlling their diameter, surface and internal structures. The introduction of ion‐exchange sites on the surface and/or inside the nanofibers provides novel high‐functional ion‐exchangers with high surface areas, high ion‐exchange and adsorption capacities, and high ionic conductivities. The present review highlights the fundamental aspects of ion‐exchange nanofibers (i.e. their size‐dependent unique properties and production methods) and their recent advances in the environment and energy applications (i.e. separation/purification processes and fuel cells). © 2018 Society of Chemical Industry

“…The effect of temperature on adsorption isotherm has been investigated under isothermal conditions over temperature range 28-58 ∘ C. Thermodynamic parameters such as free energy change (ΔG ∘ ), enthalpy change (ΔH ∘ ) and entropy change (ΔS ∘ ) can be calculated using the following equations: 19,20 ΔG ∘ = −RT lnK p (8) where K p is thermodynamic equilibrium constant, which can be determined by plotting ln(q e /C e ) versus q e and extrapolating to zero q e . Based on Van't Hoff plot of lnK p versus 1/T with T as absolute temperature (figure not shown), ΔH ∘ and ΔS ∘ can be derived from slope and intercept, respectively.…”

“…In previous studies, adsorption process due to the low cost and high efficiency is the most popular method for the removal of heavy metal ions [3,4]. The nanofibrous adsorbents prepared by electrospinning process due to high surface area and porous structure have been widely used in adsorption of heavy metal ions [5][6][7][8][9][10][11]. Chitosan is produced by the deacetylation of polysaccharide chitin.…”
