The adsorption ability of activated carbon, chitosan, and chitosan/activated carbon composite for cadmium separation from aqueous solution was analyzed via statistical physical modeling. The equilibrium data were analyzed by Langmuir, Hill, double layer model, and the multi-layer model with saturation isotherm models. Results showed that the multi-layer model with saturation could well describe...

ZnO/activated carbon nanocomposites (ZnO/ACns) were synthesized by applying two different solid-state and precipitation methods. Precipitation method was initiated with zinc chloride and sodium hydroxide as starting materials in the presence of activated carbon. The synthesized sample was calcined at 250 °C for 1 h. The preparation of nanocomposite by solid-state method was accomplished by heat...

Toluidine Blue O (TBO) is a cationic dye which is extensively used in the industries. In the present paper a simple and efficient wet chemical method was introduced for removal of TBO from waste aqueous solution. Magnetic multi-walled carbon nanotubes were synthesized using commercially available multi-wall carbon nanotubes and magnetic iron oxide nanoparticles which were examined for removal o...

adsorption of 1-butanol, phenol, and p-nitrophenol on activated carbon havebeen studied. the results were used to testifying the validity of different modelsbased on thermodynamic principles: freundlich, langmuir and henry isotherms.the maximum capacity of adsorbent for three compounds was determined, theconstants of equilibrium were determined by freundlich isotherm and virialisotherm expressi...

Abstract Magnetic activated carbon (Fe 3 O 4 -AC) is made using Fe and as primary materials to adsorb Cr(VI) in simulated wastewater. The Response Surface Method (RSM) optimizes the experimental parameters (pH, temperature, initial solution concentration, dosage). impacts of various elements are explored determine ideal reaction conditions for maximum elimination. According data, interaction be...

the present work was carried out to evaluate the removal of p-nitrophenol by adsorption onto olive cake based activated carbon having a bet surface area of 672 m²/g. the batch adsorption experimental results indicated that the equilibrium time for nitrophenol adsorption by olive cake-based activated carbon was 120min. the adsorption data was modeled by equilibrium and kinetic models. the pseudo...
