Stability Determination of the Modified Activated Carbon to Adsorb Thiophenic Compounds from Model Diesel Fuel

The main objective of this research is stability determination of activated carbon adsorbent at fixed bed adsorption column for desulfurization of diesel fuel by mathematical modeling. This model is based on mass balances. Equations that are the outcome of mass balances are known as the second degree of partial differential equations, and they must be solved together simultaneously...

Chemically modified activated carbon with ethylenediamine for

Carbon active chemically bonded ethylenediamine as one sorbents successfully were applied for the enrichment of trace amount of some metal ions. The influences of the variables including pH, amount of solid phase, sample flow rate, type and condition of eluting solution and sample volume on the metal ions recoveries were investigated. The method has high sorption-preconcentration efficiency eve...

The efficiency of modified powdered activated carbon for removal of ammonia nitrogen from aqueous solution: a process optimization using RSM (Response Surface Methodology), adsorption isotherm and kinetic study

The objective of this study was to determine the performance of modified commercial powdered activated carbon (MCPAC) in removal of ammonia from aqueous solution. The effects of adsorbent dosage (0.5–1.5 g/L), ammonia concentration (100–200 mg/L), pH (3 to 9) and contact time (2 to 120 min) were examined. In this study, experiments were performed based on Response Surface Methodology (RSM). The...

Application of magnetic particles modified with amino groups to adsorb copper ions in aqueous solution.

A magnetic adsorbent can be easily recovered from treated water by magnetic force, without requiring further downstream treatment. In this research, amine-functionalized silica magnetite has been synthesized using N-[3-(trimethoxysilyl)propyl]-ethylenediamine (TPED) as a surface modification agent. The synthesized magnetic amine adsorbents were used to adsorb copper ions in an aqueous solution ...
