Reactive and Hydraulic Behavior of Permeable Reactive Barriers Constituted by Fe0 and Granular Mixtures of Fe0/Pumice
چکیده انگلیسی

The objective of the present work is to analyze, by means of column tests, the reactivity and hydraulic long term behavior of the zero valent iron (Fe0) and of a granular mixture Fe0/pumice, for the remediation, through the Permeable Reactive Barriers technology, of nickel contaminated groundwater. The reactive behavior was studied by analyzing nickel concentration data, through a first order kinetic model in order to determine the thickness of a hypothetical PRB and its variation over time.The hydraulic conductivity behavior was studied through a numerical-statistical geometrical model developed by the authors. Expansive iron corrosion, precipitation of reaction products and gas formation are the processes considered.
