Adsorption of styrene on activated carbon and regeneration of spent activated carbon.

Optimization of chemical regeneration procedures of spent activated carbon

The chemical regeneration of granular activated carbon exhausted in a petrochemical wastewater unit was investigated. Gas chromatography and energy-dispersive X-ray spectroscopy demonstrated that spent activated carbon carries large types of organic and inorganic materials. Diverse chemical solvents were adopted in comparison with traditional chemical solvents and regeneration efficiency was in...

Adsorption of styrene monomer on activated carbon.

Styrene is discharged particulary from the factories of styrene resin and synthetic rubber, and it was listed as one of the offensive odor substances by the Offensive Odor Control Law in Japan at 1976. Styrene vapor has stimulating action on eye (STEWART et al. 1968) and membrana of nose and trachea (STEPHENSON & FOSDICK 1960). It has toxic effects on blood cells and liver (KATZ 1962), and nerv...

Statistical physics modeling of equilibrium adsorption of cadmium ions onto activated carbon, chitosan and chitosan/activated carbon composite

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...

Hydrogen Adsorption on Activated Carbon

The adsorption of hydrogen on carbon nanotubes and activated carbons has generated considerable interest in relation to hydrogen storage for fuel cells applications[1-3]. However, the widespread use of hydrogen as a fuel is limited by the lack of a convenient and cost-effective method of hydrogen storage. Adsorption of supercritical hydrogen is limited by the low interaction energy between hydr...
