Adsorption of Ni(II) and Cd(II) from water by novel chelating sponge and the effect of alkali-earth metal ions on the adsorption
TL;DR: Although the presence of alkali-earth metal ions in solution decreased Ni(II) and Cd( II) removal, PVA-M-H still retained more than 60 and 80% of its adsorption capacity even as the concentration of Ca(2+) and Mg(2%) was up to 10mmolL(-1), respectively.

Simultaneous removal of copper(II), lead(II), zinc(II) and cadmium(II) from aqueous solutions by multi-walled carbon nanotubes
TL;DR: In this paper, the effect of carbon nanotubes mass, contact time, metal ions concentration, solution pH, and ionic strength on the adsorption of heavy metals from aqueous solution by MWCNTs was studied kinetically using different kinetic models.

Isotherm, kinetic and thermodynamic studies of lead and copper uptake by H2SO4 modified chitosan.
Azlan Kamari,W. S. Wan Ngah +1 more
TL;DR: Thermodynamic parameters such as free energy change, enthalpy change, entropy change and entropy change were determined and the adsorption process was found to be both spontaneous and exothermic.

One-pot preparation of amine-rich magnetite/bacterial cellulose nanocomposite and its application for arsenate removal
TL;DR: The presence of amine surface-functionalized magnetite nanoparticles on the surface of cellulose nanofibrils not only significantly enhanced the thermal and mechanical properties but also the amine content of the nanostructured bacterial cellulose pellicle.
