Document Type and Number:
WIPO Patent Application WO/2018/168751
Kind Code:
A1
Abstract:
This insolubilization treatment agent is used for the purpose of insolubilizing a harmful substance that contains a heavy metal, and is characterized by containing a metal salt of an inorganic acid, which functions as an oxidant, an inorganic acid, inorganic porous particles, an inorganic low-molecular-weight material flocculant and an inorganic high-molecular-weight material flocculant. The metal salt of an inorganic acid is preferably at least one substance selected from among ferrous sulfate, ferric sulfate, ferric nitrate and ceric ammonium nitrate; the inorganic acid is preferably at least one substance selected from among sulfuric acid, nitric acid and hydrochloric acid; and the inorganic porous particles are preferably particles formed from at least one substance selected from among montmorillonite, vermiculite, kaolinite and zeolite.
