Retention And Transport Of Hexavalent Chromium In Calcareous Karst Soils, İrfan Yolcubal, Ni̇hat Hakan Akyol

Turkish Journal of Earth Sciences

Hexavalent chromium, which is a highly toxic and soluble form of the element chromium, is a common soil and groundwater contaminant found in many contaminated sites throughout the world and poses a serious risk to human health when released into environment. The objective of this study was to determine transport and retention behaviour of aqueous Cr(VI) species in a highly calcareous and alkaline top soil of a karst system that is vulnerable to contamination. Batch sorption studies and column experiments conducted at both saturated and unsaturated steady-state flow conditions were used to evaluate the sorption/desorption and the transport of Cr(VI) …
