Adsorption of heavy metal ions by sawdust of deciduous trees.
TL;DR: The adsorption of heavy metal ions from synthetic solutions was performed using sawdust of beech, linden and poplar trees, and the ion exchange mechanism was confirmed assuming that the alkali-earth metals from the adsorbent are substituted by heavyMetal ions and protons.

Effect of synthesis methods on magnetic Kans grass biochar for enhanced As(III, V) adsorption from aqueous solutions
TL;DR: In this article, the effects of synthesis methods on the fabrication of Kans grass straw/biochar (KGS/KGB) with Fe3+/Fe2+ by chemical co-precipitation and subsequently pyrolyzing at 500°C for 2 and 4h were studied in details.

Removal of perfluorooctane sulfonate from aqueous solution by crosslinked chitosan beads: sorption kinetics and uptake mechanism.
TL;DR: The uptake mechanisms including electrostatic and hydrophobic interactions were identified to be responsible for PFOS sorption, and the hemi-micelles and micelles may form in the porous structure due to high PFOS concentrations within the adsorbent, which had the main contribution to the high sorption capacity.
