Mercury (II) adsorption process from an aqueous solution through activated carbon blended with fresh pistachio green shell powder.

In this research, fresh pistachio green shell as an agricultural waste was blended with activated carbon to study the adsorption process of mercury (II) from several aqueous solutions with various concentrations. Central Composite Design under Response Surface Methodology was statistically used to consider the independent variables involving pH, contact time, fresh pistachio green shell powder dosage, initial concentration of mercury (II) and activated carbon dosage effects on the mercury (II) removal. pH of 6.

Simulation of landfill leachate treatment using electro-Fenton technique.

The operating parameters in the electro-Fenton process were simulated using computational fluid dynamics (CFD). The effects of H2O2/Fe(2+) molar ratio, current density, pH and reaction time were numerically investigated. The results were compared with the experimental data.
