A hybrid adsorbent (CES), coffee grounds, eggshell powder and sericite as a binder, was prepared to remove Pb(II) from aqueous solution. The Fourier-transform infrared spectroscopy analysis showed ...

A research team unveils a microwave-assisted, two-step activation strategy that converts corn straw into a hierarchically porous biochar capable of efficiently capturing CO₂.

A research team demonstrates that common agricultural and forestry residues—flax shives and eucalyptus sawdust—can be transformed into powerful magnetic carbon-based adsorbents capable of removing the ...

Adsorption is a phenomenon in which molecules or ions from a fluid phase (gas or liquid) are attracted and retained on the surface of a solid phase (adsorbent). Adsorption is different from absorption ...

Gas physisorption is an important tool for the characterization of porous solids and fine powders. The initial IUPAC report on gas physisorption, published in 1985, was dedicated to the determination ...
