Reactive fronts in chemically heterogeneous porous media: Experimental and modeling investigation of pyrite oxidation

The spatial distribution of reactive minerals in subsurface porous media is an important control for groundwater quality. In this study we investigate pyrite oxidation reactive fronts in chemically heterogeneous porous media by combining laboratory experiments and reactive transport modeling. We performed experiments in different setups including batch, 1-D column, and 2-D flow-through systems. The flow-through experiments were performed in...
