Sorption studies of uranium and thorium on activated carbon prepared from olive stones: Kinetic and thermodynamic aspects

Effect of Solution pH on the Removal of Paracetamol by Activated Carbon of Dende Coconut Mesocarp

“…As adsorbents, activated carbons from biomass residues have been widely studied. Among these residues stand out cork powder 6 , peach stones, and PET bottles 7 , coconut endocarp and palm endocarp 8 , olive stone 9 , tobacco residue 10 sisal waste 11 , mangosteen peel 12 , coconut mesocarp 13 , oil palm empty fruit bunch, bamboo stem, coconut shells 14 . Indeed, researchers have been seeking the best adsorbent to solve a local problem through the available natural disposals.…”

Equilibrium, kinetic and thermodynamic studies on the removal of U(VI) by low cost agricultural waste

“…In many developing countries, the lowcost, high sorption capacity and easy regeneration of agricultural biowastes has focused attention on their use for the remediation of heavy metals from wastewater. Biosorbents including citrus waste [3], bark [7], tea waste [8], pine sawdust [9], wood powder, wheat straw [10] and activated carbon prepared from olive stones [11] have shown potential for U biosorption.…”

Study on adsorption characteristics of uranyl ions from aqueous solutions using zirconium hydroxide

“…Various methods have been proposed to remove uranyl ions from wastewater, such as chemical precipitation [5], solvent extraction [6,7], ion exchange [8,9] and adsorption [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24]. Adsorption is a desirable method due to its high efficiency, economical, ecofriendly operation.…”

“…In recent years, numerous studies have been conducted to remove uranyl ions from aqueous solutions using various adsorbents, such as zeolites [11,12], clays [13], biological adsorbents [14,15], chemically modified adsorbents [16][17][18][19], and polymeric adsorbents [20][21][22][23][24]. However, these adsorbents suffer from one or more drawbacks.…”
