The fundamental mechanism of aqueous contaminant removal by metallic iron
Contaminant co-precipitation with continuously generated and transformed iron corrosion products has received relatively little attention in comparison to other possible removal mechanisms (adsorption, oxidation, precipitation) in Fe/H2O systems at near neutral pH values. A primary reason for this is that the use of elemental iron (Fe0) in environmental remediation is based on the thermodynamic...
متن کاملAqueous contaminant removal by metallic iron: Is the paradigm shifting?
Chemical reduction has long dominated thinking about the mechanism of aqueous contaminant removal in the presence of metallic iron (e.g. Fe/H2O systems). However, a large body of experimental evidence indicates that chemical reduction is not adequate to satisfactorily explain the efficiency of Fe/H2O systems for several substances or classes of substances. By contrast, the alternative approach,...
متن کاملMechanism of uranium removal from the aqueous solution by elemental iron.
The effectiveness of elemental iron (Fe(0)) to remove uranium (U) from the aqueous phase has been demonstrated. While the mitigation effect is sure, discrepancies in the removal mechanism have been reported. The objective of this study was to investigate the mechanism of U(VI) removal from aqueous phases by Fe(0). For this purpose, a systematic sequence of bulk experiments was conducted to char...
متن کاملInvestigation of Phenol Removal by Proxy-Electrocoagulation Process with Iron Electrodes from Aqueous Solutions
Background: Phenol as an aromatic hydroxyl compound are considered as a priority pollutant. Because of their stability, solubility in water and high toxicity had health important. Methods: In the present experimental study, electrocoagulation reactor by iron electrodes are used in the presence of hydrogen peroxide to phenol removing from aqueous solutions. Effects of variables including ...
متن کاملEvaluation the efficiency of magnetic-metallic chitosan nanocomposite adsorbent in the removal of tetracycline antibiotic from aqueous solutions
Background and Objective: Antibiotics are considered due to health and environmental problems and therefore they counted as a major threat to human health. The aim of this study was to determine the absorption efficiency of magnetic-chitosan nanocomposite in the removal of antibiotic tetracycline from aqueous solutions. Materials and Method: In this study, the experiments were performed by spec...
