| titleOfInvention | Method for producing ferrous heavy metal immobilizing agent |
| abstract | The present invention relates to a method for producing an iron-based heavy metal immobilizing agent comprising an aqueous solution containing ferrous salt and ferric salt, without using ferrous sulfate salt or ferrous salt aqueous solution as a raw material. The iron-based heavy metal immobilizing agent can be produced stably in an apparatus and in a short time. A ferrous sulfate aqueous solution is brought into contact with a metallic iron-based reducing agent to reduce ferric iron in a polyferric sulfate aqueous solution to produce a ferrous salt aqueous solution, and then the ferrous iron is prepared. It is proposed to produce the iron-based heavy metal immobilizing agent by mixing an aqueous salt solution and a new aqueous ferric sulfate solution. [Selection] Figure 1 |
