Journal ArticleDOI
Effects of the oxidation degree of graphene oxide on the adsorption of methylene blue.
TL;DR: The binding features of the MB loaded GO gradually change from MB molecule parallel stacking on graphite plane through hydrophobic π-π interaction to vertical standing via electrostatic interaction with increasing OD, resulting in a significant improvement of MB uptakes.
Journal ArticleDOI
Preparation of chitosan/poly(acrylic acid) magnetic composite microspheres and applications in the removal of copper(II) ions from aqueous solutions.
TL;DR: Experimental results revealed that the CS/PAA- MCM had greater adsorption capacity than CS-MCM, and PAA played an important role for the adsorbent of Cu(II) ions, which indicated the significant separability of the MCM in the aqueous suspensions.
Journal ArticleDOI
Flocculation of both anionic and cationic dyes in aqueous solutions by the amphoteric grafting flocculant carboxymethyl chitosan-graft-polyacrylamide.
TL;DR: The grafted polyacrylamide chains were found to contribute much to the improved bridging and sweeping flocculation effects, but reduced charge neutralization flocculations for the effect of charge screening.
Journal ArticleDOI
Evaluation of the flocculation performance of carboxymethyl chitosan-graft-polyacrylamide, a novel amphoteric chemically bonded composite flocculant
TL;DR: Different flocculation mechanisms play key roles at various pH levels, resulting in substantially varied flocculations kinetic processes under three pH conditions, systematically evaluated by light scattering in combination with fractal theory, as well as by traditional turbidity and zeta potential measurements.
Journal ArticleDOI
Enhanced and selective adsorption of copper(II) ions on surface carboxymethylated chitosan hydrogel beads
TL;DR: In this article, the surface carboxymethylated chitosan beads (CMC) provided not only enhanced but also improved selective adsorption for copper(II) (Cu(II)) ions from lead (Pb) and magnesium (Mg) ions in aqueous solutions.
