摘要
An improved method for removal of fluorine from ground water and of fluorine and chromium simultaneously from industrial waste waters is presented. The process consist of two stages, first iron(II) and calcium hydroxide solutions are added and the sediment is separated. In the second stage, after acidification, electrocoagulation using aluminium anode is applied, then, after further lowering of pH by an acid, the formed aluminium hydroxide with sorbed fluorine is removed by settling and filtration.
