In this work, the fast remediation of tert-butyl mercaptan from the polluted soil via a bimetallic Fenton treatment that included Fe2+/Fe3+/Fe0/Cu2+ in the presence of gasoline was studied. The analysis of variance and the Pareto analysis resulting from the central composite design (CCD) showed that the H2O2, CuSO4<...

The purpose of this study was the investigation of the removal of phenol with nanoparticles zero valent iron and iron powder. The effect of various parameters such as initial concentration, pH, contact time, and dosage of NZVI and Fe powder was examined, and a Central Composite Design (CCD) was then applied to appraisal the effect of these variables. The chemical and physical characteristic...

This study investigated the morphological and mineral features of nano zero-valent (nZVI)-induced iron precipitation on quartz particles. Lead was employed as artificial contaminant, while used to mimic inert solid particles in soil. The characterisation indicate that minerals precipitated heterogeneously surface with plush-like flake-like structures. They are made deuterogenic plumbiferous fer...

Nanoscale zerovalent iron (nZVI) was synthesized and employed for treating chromium(VI) containing aqueous solution through adsorption using a series of microcosm experiments. The experiments were then performed to study the effects light nonaqueous phase liquid, toluene, on Cr(VI) removal by nZVI. Results showed that maximum efficiency almost 90% achieved within 300 min treatment process, whil...

Zerovalent iron nanoparticle (nZVI) technology has been found to be promising and effective for soil groundwater remediation. This paper shows the results of two batch tests (Test A Test B) carried out assess capacity nZVI remediate arsenic (As)-contaminated water. A, performed with batches tap water contaminated by arsenic, a concentration equal 10 mg ? L?1, showed significant reduction As con...
