Hematite, arsenite adsorption

Ona-Nguema, G., Morin, G., Juillot, F. et al. (2005) Jr. EXAFS analysis of arsenite adsorption onto two-line ferrihy-drite, hematite, goethite, and lepidocrocite. Environmental Science and Technology, 39(23), 9147-55. [Pg.222]

Kinetics of Arsenic Adsorption. Arsenite adsorption on hematite is rapid, attaining equilibrium within 50 minutes and follows a first-order adsorption rate expression (42). The removal of arsenite is partially diffusion controlled and... [Pg.170]
