“…Besides, the pores structure of this CTS membrane was interconnected and symmetric led to being better dynamic adsorption through filtration. The case of NEMs, both the PAN and CTS layers all were bead-free nanofibers, use of metal oxides (ZnO and TiO 2 ) nanoparticles into PAN/CTS nanofibers membrane made the electrospinning solution more viscous; therefore, the surface of PAN/CTS/metal oxides nanoparticles (PAN/CTS/MO) membrane be rougher [ 131 ]. These changes in the surface morphological structure of AMs will influence to the heavy metal ions adsorption efficiency from aqueous solution.…”

Water is a significant natural resource for humans. As such, wastewater containing heavy metals is seen as a grave problem for the environment. Currently, adsorption is one of the common methods used for both water purification and wastewater treatment. Adsorption relies on the physical and chemical interactions between heavy metal ions and adsorbents. Adsorptive membranes (AMs) have demonstrated high effectiveness in heavy metal removal from wastewater owing to their exclusive structural properties. This article examines the applications of adsorptive membranes such as polymeric membranes (PMs), polymer-ceramic membranes (PCMs), electrospinning nanofiber membranes (ENMs), and nano-enhanced membranes (NEMs), which demonstrate high selectivity and adsorption capacity for heavy metal ions, as well as both advantages and disadvantages of each one all, are summarized and compared shortly. Moreover, the general theories for both adsorption isotherms and adsorption kinetics are described briefly to comprehend the adsorption process. This work will be valuable to readers in understanding the current applications of various AMs and their mechanisms in heavy metal ion adsorption, as well as the recycling methods in heavy ions desorption process are summarized and described clearly. Besides, the influences of morphological and chemical structures of AMs are presented and described in detail as well.

“…It could be said that both composites have continuous and long morphologies.As seen, ACNF/Fe 2 O 3 composite shows a relatively thick cylindrical fibers with an average diameter of 160 nm ± 10 nm, whereas ACNF/Co 3 O 4 composite reveals a rough surface and thinner fibers with an average diameter of 130 ± 15 nm. As seen, the rough surface of ACNF composites could be attributed to the presence of metal oxide NPs agglomerated[29].…”

In the present study, we successfully prepared two different electrospun polyacrylonitrile (PAN) based-activated carbon nanofiber (ACNF) composites by incorporation of well-distributed Fe 2 O 3 and Co 3 O 4 nanoparticles (NPs). The influence of metal oxide on the structural, morphological, and textural properties of final composites was thoroughly investigated. The results showed that the morphological and textural properties could be easily tuned by changing the metal oxide NPs. Even though, the ACNF composites were not chemically activated by any activation agent, they presented relatively high surface areas (S BET ) calculated by Brunauer–Emmett–Teller (BET) equation as 212.21 and 185.12 m 2 /g for ACNF/Fe 2 O 3 and ACNF/Co 3 O 4 composites, respectively. Furthermore, the ACNF composites were utilized as candidate adsorbents for CO 2 and CH 4 adsorption. The ACNF/Fe 2 O 3 and ACNF/Co 3 O 4 composites resulted the highest CO 2 adsorption capacities of 1.502 and 2.166 mmol/g at 0 °C, respectively, whereas the highest CH 4 adsorption capacities were obtained to be 0.516 and 0.661 mmol/g at 0 °C by ACNF/Fe 2 O 3 and ACNF/Co 3 O 4 composites, respectively. The isosteric heats calculated lower than 80 kJ/mol showed that the adsorption processes of CO 2 and CH 4 were mainly dominated by physical adsorption for both ACNF composites. Our findings indicated that ACNF-metal oxide composites are useful materials for designing of CO 2 and CH 4 adsorption systems.

Chitosan is a promising environmentally-friendly polymer with a wide range of applications in biological, medical and water treatment fields. Recent research in chitosan-based electro spun nanofibers has led to the very cost-effective and efficient removal of toxic metal ions from solutions that are extremely important in today's pollution-ridden world. Nanofiber fabrication of chitosan blends can easily be done by the novel electrospinning technique. Because of their high adsorption capability, metal chelation ability, nontoxicity, biocompatibility, biodegradability, hydrophilicity, and cost effectiveness, chitosan-based nanofibers have seen rapid growth in water treatment applications. This review outlines the ability of electrospinning produced chitosan-based nanofibers to remove toxic metals. The primary goal of this review is to provide current information on various chitosan blend nanofibers that may be useful in water purification, as well as to encourage further research in this area.
