Specific adsorption of hydrolyzed chromium species on kaolinite surface was studied. Electrokinetic behavior of kaolinite particles in aqueous solutions in the presence of CrCl3 showed that the hydrolyzed chromium species can adsorb on kaolinite surfaces and reverse its charge. This adsorption reached the maximum near the precipitation pH (ppt) of chromium hydroxide. The adsorption followed Langmuir isotherm and was irreversible. It might be resulted from hydrogen bonding between the hydrolyzed metal species and kaolinite surfaces. A novel chemical adsorption model was proposed between kaolinite surfaces and the hydrolyzed multivalent metal species. © 2012 Copyright Taylor and Francis Group, LLC.
