Use of carboxylated cellulose nanofibrils-filled magnetic chitosan hydrogel beads as adsorbents for Pb(II).
TL;DR: Experimental results revealed that the Pb(II)-loaded m-CS/PVA/CCNFs hydrogels could be easily regenerated in weak acid solution and the adsorption effectiveness of 90% can be maintained after the 4 cycles.
Journal ArticleDOI
Adsorption of platinum(IV) and palladium(II) from aqueous solution by thiourea-modified chitosan microspheres
TL;DR: The adsorbent was stable without loss of the adsorption capacity up to at least 5 cycles and the desorption efficiencies were above 95% when 0.5 M EDTA-0.5M H2SO4 eluent was used.
Journal ArticleDOI
Characteristics of equilibrium, kinetics studies for adsorption of fluoride on magnetic-chitosan particle
TL;DR: The magnetic-chitosan particle was prepared and characterized by the SEM, XRD, FT-IR and employed as an adsorbent for removal fluoride from the water solution in the batch system to propose the major mechanism of fluoride adsorption onto the heterogeneous surface of magnetic- chitOSan particle.

Biosorption of nickel on blank alginate beads, free and immobilized algal cells
TL;DR: In this paper, the potential use of blank alginate beads, free (non-immobilized) live and dead and immobilized dead algal cells for the removal of nickelions from aqueous solutions was investigated.
Journal ArticleDOI
A novel adsorbent TEMPO-mediated oxidized cellulose nanofibrils modified with PEI: Preparation, characterization, and application for Cu(II) removal.
TL;DR: Kinetic study showed that the PEI grafting increased the initial adsorption rate of the TOCN-PEI compared with the adsorbents without PEI, and the kinetics curve suited the pseudo-second-order model better and the equilibrium data well fitted the Langmuir model.
