Rapid Adsorption of Crystal Violet onto Magnetic Zeolite Synthesized from Fly Ash and Magnetite Nanoparticles

This work reports the adsorption of crystal violet (CV) dye onto magnetic zeolite (MZ) nanoparticles, synthesized by direct fusion of fly ash (FA) and magnetite particles. The synthesised MZ showed high capacity for CV dye adsorption, removing 95% of the dye at an equilibrium adsorption time of 10 min and 25 ̊C. The effects of adsorbent dosage, dye concentration, and pH, on adsorption were evalu...

Heavy Metal Ions Adsorption on Chitosan-Magnetite Microspheres

Composite chitosan-magnetite microparticles (Fe-Cc) were evaluated as a new adsorbent for cobalt and nickel ion separation from aqueous solutions. Sorption batch experiments were conducted for optimizing the pH, initial target ion concentration and adsorbent amount. The experimental data were fitted using Langmuir, Freundlich, and respectively DubininRadushkevich isotherm models. The Langmuir m...

Adsorption of Metallic Ions onto Chitosan: Equilibrium and Kinetic Studies

Equilibrium isotherms and the adsorption kinetics of heavy metals onto chitosan were studied experimentally. Chitosan, a biopolymer produced from crustacean shells, has applications in various areas, particularly in drinking water and wastewater treatment due to its ability to remove metallic ions from solutions. The adsorption capacity of chitosan depends on a number of parameters: deacetylati...

Adsorption and desorption of copper(II) ions onto garden grass.

The garden grass (GG) was firstly used to remove copper(II) from water as bioadsorbent. From the results of characterisation, the GG had the merits of high specific surface area, significant adsorption sites and functional groups. Copper-adsorption significantly depends on the initial copper concentrations, contact time, pH, adsorbent doses, particle sizes and temperature. The positive values o...

Adsorption of copper ions onto microwave stabilized heavy metal sludge.

Microwave stabilized heavy metal sludge was used as an adsorbent to remove the copper ions from aqueous solution. The adsorption characteristics of copper on the stabilized-sludge were studied by various models, such as Freundlich and Langmuir isotherm equation. Results show that the pH(zpc) of stabilized-sludge was at 9.2-9.5. Moreover, the adsorption of copper ions onto the stabilized-sludge ...
