Application of XDMT in three-dimensional visualization of arsenic aggregates in porous media

PENG Daoping HUANG Tao HE Yulong(School of Geosciences and Environmental Engineering,Southwest Jiaotong University,Chengdu,610031,China)  
This paper applied the X-ray difference micro-tomography to characterize the distribution of arsenic aggregates within porous media by scanning a series of laboratory prepared arsenic samples and arsenic-rich fluvial sediments from a river.Tools like Avizo 6 and Blob3D were used to process the tomographic data and visualize the 3D distribution of arsenic aggregates in the media.3D visualization showed that arsenic accumulated in the pore space and grain surface of the media.Arsenic aggregates of different sizes had distinctly different morphologies: small aggregates tended to be spherical while big aggregates were relatively flat.These results show that difference micro-tomography can be used to observe the variation of internal structure caused by deposition,without destructions to the porous media.
