Illite spatial distribution patterns dictates Cr(VI) sorption macrocapacity and macrokinetic

Wang, LI
This data set examines the largely unexplored role of illite spatial distribution patterns in dictating sorption of Cr(VI). Flow-through experiments were carried out at 0.6, 3.0 and 15.0 m/day using columns packed with the same illite and quartz mass however with different patterns and permeability contrasts. Column-scale sorption macrocapacity and macrorates were found to decrease with transport connectivity, a quantitative measure of heterogeneity characteristics. At 0.6 and 3.0 m/day, well-connected low permeability illite zones oriented in the flow-parallel direction leads to diffusion-controlled mass transport limitation to access sorption sites, leading to up to 1.4 order of magnitude lower macrocapacity and macrorates compared to those in minimally-connected columns with well-mixed illite and quartz. Insights gained here bridge gaps between laboratory and field application, advance predictive understanding of reactive transport processes in natural heterogeneous subsurface.
