Novel thin film composite membrane fabricated by mixed matrix nanoclay/chitosan on PVDF microfiltration support: Preparation, characterization and performance in dye removal

Utilization of a Novel Chitosan/Clay/Biochar Nanobiocomposite for Immobilization of Heavy Metals in Acid Soil Environment

“…The presence of these functional groups gives chitosan a cationic polyelectrolyte character and enables it to chelate metal ions [9,10]. Since it is a hydrophilic biopolymer, it is potentially biocompatible, environmentally friendly, and suitable to be used in sustainable materials (e.g.…”

“…Since it is a hydrophilic biopolymer, it is potentially biocompatible, environmentally friendly, and suitable to be used in sustainable materials (e.g. adsorbents, coating materials, membranes) [8,9]. Nanoclays including modified and unmodified montmorillonite clays (commercially referred to as the Cloisite series) are widely used as nanofillers or additive materials to improve various physical properties of polymers, such as reinforcement.…”

“…The remarkably large adsorption capacity of this material for metals is mainly due to the specific layered structure and existence of exchangeable hydrated cations [11]. Chitosan based nanocomposites containing MT have been used for dye removal [9,[12][13][14][15] and sorption of heavy metals [16][17][18][19] from effluents. However, their effect on contaminated soils has not yet been evaluated.…”

Improved Performance of CaCl 2 Incorporated Polyethersulfone Ultrafiltration Membranes

“…In general, organic polymers are more suitable starting materials for the preparation of industrial grade membranes, especially for effluent treatment [4]. Several polymers such as polyvinylidene fluoride [5][6][7][8], polysulfone [9][10][11], polyacrylonitrile [12,13], polyethersulfone [14][15][16][17] and cellulose acetate [18][19][20] have been reported for the development of microfiltration (MF) and ultrafiltration (UF) membranes for various applications.…”

Mitigation of fouling of polyethersulfone membranes using an aqueous suspension of cellulose nanocrystals as a nonsolvent

“…However, there are other approaches regarding the fabrication of nano-enhanced membranes such as coating them on the membrane surface (Kim et al 2013), adding them as a thin film containing nanomaterial and a supporting media (Daraei et al 2013c), and even adding them to a coagulation bath (Kim and Van der Bruggen 2010;Wang et al 2011). It was shown that adding nanoparticles in the nonsolvent instead of dope solution might result in better dispersion of nanoparticles on the surface as the main operating part of the membrane .…”
