In this study, degradation of p-chlorophenol (p-CP) was evaluated using persulfate (PS) activated zerovalent iron (ZVI) based ultraviolet (UV) in a bench scale photoreactor. The effect of operational parameters such as solution pH (3, 7, and 11), reaction time (0-60 minutes), ZVI dosage (0.15, 1.25, 0.5, 1, and 1.5 mM), PS concentration (0.5, 1.5, 2, 2.5, 3, and 4 mM), and initial p-CP concentr...

The presence of arsenic in water for human consumption is concern, especially developing countries, and the design simple economic treatments removal imperative. In this paper, three low-cost technologies were evaluated As(V) or As(III) (5 mg L?1) removal: (1) zerovalent iron (Fe(0)), as powdered (?Fe(0)) wool (wFe(0)); (2) coagulation-flocculation with Al2(SO4)3 FeCl3; (3) adsorption on a natu...

Hydrogen is becoming important clean energy while zerovalent iron (ZVI) and ferroferric oxide are of great interest to many applications including environmental remediation chemical catalysis. Here, we report production hydrogen, octahedron by etching Al–Fe alloys using NaOH solutions. The rate hydrogen generation increased with increasing concentration the alloy's particle size decreasing Fe c...
