Radiotracer method in study of reactive transport across chemical gradients in porous media
- 38 Downloads
Modeling and experimental approaches to study reactive transport across chemical gradients in porous media are presented. Particular emphasis is placed on a purposeful experimental setup to obtain information necessary for model calibration and verification. As example, diffusion tube experiments on the layered acidic jarosite/alkaline coal fly ash system have been carried out using radiotracers 3H+, 22Na+, and 59Fe3+. Such radiotracer diffusion tube experiments provide modelers with reliable information incorporating some of the complexities observed in the environment such as local heterogeneities.
