Abstract：The oxidation law of elemental mercury using KClO oxidant was studied in the bubble reactor. The effects of initial oxidizing solution concentration, reaction temperature, pH and mercury concentration in the inlet of the reactor on mercury oxidative absorption in KClO were investigated. The results indicate that higher concentrations of KClO fa-vor Hg~0 removal, with a greater efficiency observed in acidic than in alkaline solution. High temperature inhibits Hg~0 absorption in aqueous absorbent. The pH value increases during the reaction process, and the reaction system depletes H~+ or produces OH~-. In conclusion, the major influencing factors on the levels of Hg~0 removal are pH and chlorite concentration in solution.
