(
MDPI
, 2021 , Article)
Lignite, as an available and low-cost material, was tested for cadmium (Cd) and copper (Cu) removal from aqueous solutions under various static experimental conditions. Experimental results showed that the removal efficiency ...
Sludge-derived biochars: A review on the influence of synthesis conditions on pollutants removal efficiency from wastewaters
(
Elsevier
, 2021 , Article)
Pyrolysis is a thermochemical process that permits the conversion of biomasses into energy (bio-oil and biogas) and a solid residue called biochar. The generation of biochar from lignocellulosic materials has been, for ...
