Abstract
Sorption of iodine on Beishan granite was studied by batch method. Great difference exists in the sorption behaviors of I− and IO3−. Under acidic condition, the sorption of IO3− improves dramatically, and IO3− could partly convert to I−. However, the sorption of I− is close to zero at all studied pH. Humic acid can slight improve the sorption of IO3−, but greatly improve the sorption of I− in acidic condition. The postulated sorption mechanisms of IO3− are electrical interaction and followed by reduction.
