Hydrothermal synthesis of LaFeO nanoparticles adsorbent: Characterization and application of error functions for adsorption of fluoride.

The adsorption of fluoride from aqueous solution by lanthanum ferrite nanoparticles (LaFeO NPs) synthesized by the hydrothermal method has been investigated. This experimental study was conducted on a laboratory scale. The effects of various operating parameters such as pH (3-11), LaFeO NPs dosage (0.

Adsorption behavior of Cu(II) and Co(II) using chemically modified marine algae.

In this study, brown algae-modified biomass Padina sanctae crucis was used for copper (Cu(II)) and cobalt (Co(II)) heavy metal ions adsorption in synthetic wastewater. The effects of solution pH and adsorption efficiency for Cu(II) and Co(II) removal from aqueous solutions were studied. In order to study the kinetic behavior of adsorption, pseudo-first-order, pseudo-second-order kinetic models, liquid film penetration, and Ritchie second-order models were used.
