Hydrogen diffusion in the apatite-water system: Fluorapatite parallel to the c-axis
apatite hydrogen diffusion H-D exchange H2O SIMS
2017/4/10
Many studies in the past decade have sought to explore the origin and evolution of water in planetary bodies based on
the hydrogen isotopic compositions of apatite. However, no investigation has stud...
Laboratory Determination of Multicomponent Effective Diffusion Coefficients for Heavy Metals in a Compacted Clay
contaminant transport diffusion coefficients heavy metals clay liner Ankara clay
2009/7/7
Diffusion and sorption of heavy-metal ions (Cd, Cr, Cu, Fe, K, Mn, Ni, Pb, and Zn) through an Ankara clay liner were studied experimentally. The Ankara clay consists of calcite, quartz, smectite and i...
