Abstract

Abstract

En 中文
• Apparent diffusion coefficients decrease with increasing dry density. • Diffusion increases with temperature following Arrhenius-type behaviour. • Selenite shows the lowest diffusion due to strong interactions with clay surfaces. • Anion exclusion affects diffusion of Cl−, SO42− and SeO32−.
