“…In addition to the formation of the new peak at 564.17 cm −1 which can be assigned to the Mg-F stretching vibration. Some other research groups have considered this innovative approach and have univocally found out that vigorously homogenizing the experimental systems yields reproducible and relevant results for ion/ligand exchange mechanism (Devi et al 2012;Margandan et al 2014;Chigondo et al 2018;Yu et al 2018;Lee et al 2017).…”

“…Therefore, there has been an increasing need to modify adsorbents using non toxic materials. Different nontoxic MgO materials have been evaluated for improvement of F − adsorption onto commercial MgO; synthesized pillar and microsphere-like MgO (Lee et al 2017), nano-sized MgO (Devi et al 2012), synthesized meso MgO (Yu et al 2018), porous MgO nanoplates (Jin et al 2016). Adsorption capacity of the porous MgO nanoplates was superior to other MgO nanomaterials.…”

The adsorption kinetics of fluoride onto limestone (LS) and Mg(OH)2-amended LS were investigated using batch adsorption technique. Data were best fitted to second-order and Elovich models. The Mg(OH)2-ameded LS showed substantial increases in F− adsorption relative to native LS. Similarity of ionic radii and charge of both F− and OH− were hypothesized to be the major cause of such increases. The OH− functional group of the surface Mg(OH)2 could be exchanged by aqueous F− through surface complexation (ligand exchange). No background effect of naturally occurring anions in F−-rich groundwater on adsorption capacity of Mg(OH)2-amended LS. The results reveal that the Mg(OH)2-amended LS can be environmentally safe and economical for F− removal.

“…They tested its degradation capacity against paraoxon-ethyl toxin, obtaining a 92% of removal in 40 min. Furthermore, Yu et al [84] reported the synthesis of MgO mesoporous nanofibers and studied the adsorption capacity against fluoride and Congo red. The bumpy morphology of the fibers obtained by electrospinning process provided more active sites for adsorption, and the MgO nanofibers exhibited a surface area of 194.17 m 2 /g.…”

In the last few decades, the development of new electrospun materials with different morphologies and advanced multifunctional properties are strongly consolidated. There are several reviews that describe the processing, use and characterization of electrospun nanocomposites, however, based on our knowledge, no review on electrospun nanocomposites reinforced with nanoparticles (NPs) based on magnesium, Mg-based NPs, are reported. Therefore, in the present review, we focus attention on the fabrication of these promising electrospun materials and their potential applications. Firstly, the electrospinning technique and its main processing window-parameters are described, as well as some post-processing methods used to obtain Mg-based materials. Then, the applications of Mg-based electrospun nanocomposites in different fields are pointed out, thus taking into account the current trend in developing inorganic-organic nanocomposites to gradually satisfy the challenges that the industry generates. Mg-based electrospun nanocomposites are becoming an attractive field of research for environmental remediation (waste-water cleaning and air filtration) as well as for novel technical textiles. However, the mayor application of Mg-based electrospun materials is in the biomedical field, as pointed out. Therefore, this review aims to clarify the tendency in using electrospinning technique and Mg-based nanoparticles to huge development at industrial level in the near future.
