Adsorption equilibrium and kinetics of polyvinyl alcohol from aqueous solution on powdered activated carbon
TL;DR: In this study, powdered activated carbon was used to remove polyvinyl alcohol (PVA) from the aqueous PVA solution and the rates of adsorption were found to conform to the second-order kinetics with good correlation.

Kinetic and thermodynamic aspects of the adsorption of Pb2+ and Cd2+ ions on tripolyphosphate-modified kaolinite clay
TL;DR: In this article, the kinetics and thermodynamics of the adsorption of Pb2+ and Cd2+ by TPP-Kaolinite clay were studied. And the results showed that the sorption of both metal ions was endothermic and spontaneous with ΔH° values of +13.94kJ-mol−1 and +24.93kJ−mol−1, respectively.

Removal of heavy metal ions from aqueous solutions with multi-walled carbon nanotubes: Kinetic and thermodynamic studies
TL;DR: In this paper, the authors used multi-walled carbon nanotubes for the removal of heavy metal ions from aqueous solutions, and the results showed that the % adsorption increased by raising the solution temperature due to the endothermic nature of the adsorbing process.
Journal ArticleDOI
Two fold modified chitosan for enhanced adsorption of hexavalent chromium from simulated wastewater and industrial effluents.
TL;DR: The sorption kinetics and thermodynamic studies revealed that adsorption of Cr(VI) followed pseudo-second-order kinetics with exothermic and spontaneous behaviour, which demonstrated applicability of ISPC for higher sample volumes.
