Adsorption of anthracene using activated carbon and Posidonia oceanica

Experimental Investigation and Modeling of CO2 Adsorption Using Modified Activated Carbon

In this research, Activated Carbon (AC) was modified using a sodium hydroxide solution for CO2 adsorption. Adsorption experiments were carried out in a batch reactor at a temperature range of 20-80°C and a pressure range of 2-10 bars to investigate kinetic, isotherm, and thermodynamic of the CO2 adsorption process. Activated carbon was modified with NaOH solution conce...

Removal of chromium (VI) from aqueous solution by adsorption using cousinia eryngioides boiss and activated carbon

Adsorption capacity of Cr (VI) onto cousinia eryngioides boiss, activated carbon was investigated in a batch system by considering the effects of various parameters like contact time, initial concentration, pH, temperature, agitation speed, absorbent dose and particle size. Cr (VI) removal is pH dependent and found to be maximum at pH 2.0. The amounts of Cr (VI) adsorbed increased with increase...

Adsorption of nitrate from aqueous solution using activated carbon-supported Fe0, Fe2 (SO4)3, and FeSO4

In this laboratory scale study, impregnated almond shell activated carbon was used as adsorbent to investigate its feasibility for nitrate adsorption from aqueous medium. The effects of activated carbon dosage and contact time have been examined in batch experiments. Experimental data show that impregnated activated carbons by Fe0, Fe2 (SO4)3, and FeSO4 were more effective than virgin almond ac...

Organic Carbon Metabolism and Carbonate Dynamics in a Mediterranean Seagrass (Posidonia oceanica) Meadow

We measured monthly dissolved oxygen (DO) changes in situ benthic incubations from March 2001 to October 2002 in a Posidonia oceanica meadow and unvegetated sediments of Magalluf Bay (Mallorca Island, Spain) to determine gross primary production (GPP), community respiration (R), and net community production (NCP). From June 2001 to October 2002, we also measured fluxes of dissolved inorganic ca...
