Use of lignite as a low-cost material for cadmium and copper removal from aqueous solutions: Assessment of adsorption characteristics and exploration of involved mechanisms
Jellali, Salah; Azzaz, Ahmed Amine; Jeguirim, Mejdi; Hamdi, Helmi; Mlayah, Ammar ( 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 ... -
Valorization of salt post-modified poultry manure biochars for phosphorus recovery from aqueous solutions: investigations on adsorption properties and involved mechanism
Hadroug, Samar; Jellali, Salah; Azzaz, Ahmed Amine; Kwapinska, Marzena; Hamdi, Helmi; Leahy, James J.; Jeguirim, Mejdi; Kwapinski, Witold... more authors ... less authors ( Springer , 2021 , Article)In this research work, raw poultry manure biochar (RPM-B) was post-modified by two metal salts and then evaluated for P recovery from aqueous solutions in batch mode. The modified biochar characterization showed that RPM-B ... -
