Description
Summary:For the first time, an efficient method for the removal of mercury from Arabian gas-condensate samples was reported. Silver nanoparticles (AgNPs) functionalized with activated carbon (AC) prepared from local date-pits were used as an adsorbent. The physical and chemical properties of AgNP-AC were characterized using surface characterization techniques, and the adsorbent was evaluated under different experimental conditions. These factors considered include AgNP concentrations, contact time, the adsorbent dosage of AgNP-AC and initial mercury concentration. Langmuir adsorption isotherm, pseudo-second-order kinetics and Weber intraparticle diffusion models were used to evaluate the adsorption properties of the AgNP-AC. The results obtained revealed that at a low contact time, 25 mM AgNPs functionalized on AC provided the highest adsorption efficiency (98%) in the removal of mercury from Arabian gas-condensate. Also, it was observed that the increase in AgNP-AC dosage and initial mercury concentration plays a significant role in the mercury removal process. With a correlation coefficient of 0.9987, the adsorption process fits the Langmuir isotherm, suggesting that the adsorption is homogenous and monolayer.
