چکیده
Due to its high oil content, the discharge of bilge water from ships is one most important pollutants in marine ecosystem. In this research, we investigated treatment for Haydarpasa Waste Collection Plant by Fenton oxidation followed granular activated carbon (GAC) adsorption. We applied following optimum operational conditions oxidation: [Fe2+]: 6 mM; [H2O2]: 30 and ratio [Fe2+]/[H2O2]: 1/5. Adsorption was performed effluent sample oxidation. The effects different adsorption periods, adsorbent concentrations, temperature, pH were examined. Additionally, Freundlich Langmuir isotherm models applied. obtained conditions: 24 h, 2 g GAC L−1, 20 °C, = 6. observed an 89.5 ± 1.9% Chemical Oxygen Demand (COD) removal efficiency under these conditions. Data generated experiments fit both well, though preferred model because former’s regression coefficient (0.90) larger than that reported (0.78). potential treat promising Plant.

Experimental and Theoretical Study on the CH4 Adsorption by Granular and Microporous Activated Carbon
Adsorbed natural gas (ANG) by Granular Activated Carbon (GAC) has been widely investigated as an alternative to CNG and LNG technologies for storage and transportation of natural gas. In the present work, a theoretical and experimental study was conducted to accurately determine the amount of adsorption of CH4 by GAC. To carry out the experiments, the volumetric method was used up to 4 MPa at c...

In this work, the removal of copper from an aqueous solution by granular activated carbon (GAC) in the presence of competitor ions was studied. A batch adsorption was carried out and different parameters such as pH, contact time, initial copper concentration and competitor ions concentration were changed to determine the optimum conditions for adsorption. The optimum pH required for maximum ads...
