Grafting of regenerated cellulose films with fibrous polymer and modified into phosphate and sulfate groups: Application for removal of a model azo-dye

Polymer-modified regenerated cellulose membranes: following the atom transfer radical polymerization concepts consistent with the principles of green chemistry

“…Cellulose membranes were grafted with polymers with various characteristics using the high catalyst ATRP technique to improve or give membranes novel properties, e.g. formation of cation- (Bayramoglu and Arica 2021;Chenette et al 2012;Liu et al 2009;Porter et al 2020;Qian et al 2013;Wang et al 2015Wang et al , 2014Zhang et al 2011), anion-exchange (Bhut and Husson 2009;Bhut et al 2008;Menkhaus et al 2010;Pan et al 2011;Qian et al 2013;Singh et al 2008b;Wei et al 2011;Zeng et al 2021) or multifunctional (Feng et al 2014;Liu et al 2014;Porter et al 2022;Yang et al 2016;Ye et al 2020;Zhao et al 2010) adsorption membrane for proteins (Bhut et al 2008;Chenette et al 2012;Himstedt et al 2013;Liu et al 2010;Qian et al 2013;Singh et al 2008b;Wang et al 2015Wang et al , 2014Zhao et al 2010) or enzymes (Feng et al 2014;Zeng et al 2021) absorption. Cation, anion or zwitterion surfaces are created by polymerization of monomers with functional group, e.g.-polyelectrolytes (Chen and Lee 2021), from the flat surface.…”

“…In this context, modification with polymers allows giving quite new properties for the membrane to separate components about their characteristics other than their molecular weight, e.g. charge and sensitivity to changes in pH (Bayramoglu and Arica 2021;Bhut and Husson 2009;Bhut et al 2008;Chenette et al 2012;Liu et al 2009;Menkhaus et al 2010;Pan et al 2011;Porter et al 2020;Qian et al 2013;Singh et al 2008b;Wang et al 2015Wang et al , 2014Wei et al 2011;Zeng et al 2021;Zhang et al 2011) or temperature (Pan et al 2010a, b), as well as hydrophobic (Ye et al 2020) or hydrophilic (Qiu et al 2013) characteristics, etc. This allows for a precise separation with a wide range of applications in many industries.…”

The efficient removal of diclofenac sodium and bromocresol green from aqueous solution by sea urchin-like Ni/Co-BTC bimetallic organic framework: adsorption isotherms, kinetics and mechanisms

“…When the temperature was at 25 1C, pH = 7, and the initial concentration of the DCF and BCG solutions was 100 mg L À1 , Ni/Co-BTC MOF with the best adsorption effect was selected to test the effect of the different adsorbent dosages on the adsorption of DCF and BCG. 45,46 The results are shown in Fig. S3 (ESI †).…”

Synthesis of Cu nanoparticles in a chitosan entrapped copolymer matrix for photocatalytic reduction of textile dye and column adsorption of heavy metal ions from water

“…Both methyl violet (MV) dye and Pb(II) heavy metal ions are found in industrial wastewater from paper pulp and textile industries [ 21 ] . In fact, functional polymer composites like polydopamine‐grafted biosilica, [ 22 ] poly(glycidyl methacrylate)‐grafted regenerated cellulose film, [ 23 ] and poly(hydroxypropylmethacrylate‐ co ‐ethyleneglycol dimethacrylate‐ co ‐glycidyl‐metharylate) terpolymer resin functionalized with sulfonic acid groups [ 24 ] were recently reported for the removal of different synthetic dyes by adsorption. In the present work, the PMNCs were used for photocatalytic reduction of low concentration of MV from water.…”
