Fabrication of amino-modified electrospun nanofibrous cellulose membrane and adsorption for typical organoarsenic contaminants: Behavior and mechanism

Efficient removal of bisphenol pollutants on imine-based covalent organic frameworks: adsorption behavior and mechanism

“…Several reports confirmed that –OH played an important role in the form of hydrogen bonds between materials and pollutants, which was conducive for the adsorption of organic pollutants. 64,65 Moreover, the absorption band corresponding to the aromatic –C N– stretching vibration in the COFs spectrum was strengthened following the adsorption of BPS/BPA. An obvious enhancement was observed for the peaks at 1510 cm −1 and 827 cm −1 , which was ascribed to the stretching vibration of C–H and the bending vibration of the aromatic rings, which finally verified the adsorption of BPS and BPA on the COFs.…”

Recent progress in cellulose-based electrospun nanofibers as multifunctional materials

“…Overviewing the research works published in last 3 years (2018-2021), various electrospun nanofibers have been successfully prepared from cellulose and cellulose derivatives in different solvent systems [12][13][14][15][16][17] . These nanofibers demonstrated promising applications in the fields of filtration, tissue engineering and biomedical engineering [18][19][20][21][22] .…”

“…(Reprinted with permission 23 , Elsevier publishing).2.2 Electrospinning of cellulose derivativesCompared to the poor solubility of cellulose, cellulose derivatives have greatly improved solubility in many organic and inorganic solvents due to changes in the structure of cellulose. Cellulose acetate (CA) is one of the most used cellulose derivatives for the production of electrospun nanofibers because CA can achieve continuous and controllable electrospinning in several conventional solvents, such as acetic acid25 , acetone/DMAC solvent13 , and acetone/DMF/water26 , and the obtained CA nanofibers can be easily hydrolysed into cellulose nanofibers. The utilization of other cellulose derivatives has also been reported recently.…”

Removal of p-arsanilic acid and phenylarsonic acid from water by Fenton coagulation process: influence of substituted amino group

“…By using these methods, organoarsenic compounds are always oxidized to As( ) or As( ). Although straight removal of p-ASA and phenylarsonic acid (PAA) by adsorption has also been studied (Chen &Huang 2012, Hu et al 2017, Liu et al 2020, they were adsorbed much less strongly compared to As( ). So oxidizing organoarsenic pollutants to As( ) and then removing the released inorganic arsenic by adsorption could be a better choice to enhance the removal e ciency of them in aqueous solution (Lan et al 2016, Xie et al 2016a, Xie et al 2019.…”
