Adsorption of Cd2+ onto apatite surface: Equilibrium, kinetics and thermodynamic studies

Characterization of chitosan- and β-cyclodextrin-modified forms of magnesium-doped hydroxyapatites as enhanced carriers for levofloxacin: loading, release, and anti-inflammatory properties

“…Its signicant adsorption prospective, ion-exchanging qualities, extended shelf life, broad surface area, exible framework, and capacity to respond to acidic and basic environments have all been pointed out as reasons for its wide applications. [25][26][27] It has bioactive, biodegradable, biocompatible, and osteoconductive functions as a biomedical compound without causing inammation or toxicity. However, its composition's hydrophilic quality reduces its potency as a vehicle for traditional drugs possessing an organic chemical structure.…”

Effect of Phosphorus Application on Eggplant Cadmium Accumulation and Soil Cadmium Morphology

“…These precipitates impede Cd transport to protoplasts and xylem, further restricting Cd movement and concentration within plant tissues [42,43]. Both MAP and DAP containing NH 4 + , H 2 PO 4 2− , and PO 4 3− form Cd(NH 4 ) 2 PO 4 and CdNH 4 PO 4 precipitates in the presence of Cd 2+ in the soil for a long period, which reduces Cd content in eggplant [44]. However, the soil in this study was alkaline and contained large amounts of metal cations such as Mn 2+ , Mg 2+ , and Na + .…”

Discussion on the thermodynamic calculation and adsorption spontaneity re Ofudje et al. (2023)

“…Ofudje et al (2023) recently published an article entitled “Adsorption of Cd 2+ onto apatite surface: Equilibrium, kinetics and thermodynamic studies” in Heliyon 9 (2023) e12971 [ 1 ]. Their results showed that the apatite synthesized by chemical method (CHAp) has excellent adsorption properties for cadmium ions.…”
