Abstract

The adsorption behavior of hazardous compounds on minerals controls their migration process in environments. Thus, it is important to investigate the adsorption behavior of the arsenic compounds on minerals to understand the migration process and to predict future fate of them in environment. In this study, we conducted adsorption experiments, As K-edge X-ray absorption fine structure (XAFS) measurements and DFT calculations for organoarsenic compounds adsorbed on ferrihydrite to understand the effects of substitution of organic functional groups on their adsorption behavior.
