Research Abstract

Flow-type hydrothermal treatments were investigated in order to accomplish detoxification and mineralization of boron resource from aqueous media which containing borate ion. Flow-type treatment by using CaCl_2 aqueous solution as supply source of Ca and boron-containing aqueous solution, which adjusted at alkali condition, could continuously mineralize boron resource and detoxify the aqueous solution.
