Physically-crosslinked hydroxyethyl cellulose-g-poly (acrylic acid-co-acrylamide)-Fe3+/silver nanoparticles for water disinfection and enhanced adsorption of basic methylene blue dye
A novel poly(acrylic acid) (PAA)-based super-adsorbent nanocomposite hydrogel as an effective dye adsorbent is prepared using non-aggregated calcium hydroxide (Ca(OH)2) nano-spherulites (CNSs) as cross-linkers.
