Quick preparation method for starch-stabilizing nanometer zero-valent iron

摘要: The invention relates to a quick preparation method for starch-stabilizing nanometer zero-valent iron. the iron is characterized in that particles can be prepared by liquid phase reduction which includes: solving soluble ferrous sulfate solution of ethyl alcohol and water; adding appropriate amount starch into with stirring uniformly; sodium borohydride drop drop, performing under condition so as obtain particles. has advantages no need nitrogen protection, low requirement on equipment, simple principle, quickness reaction capability preparing large quantity powder are achieved; macromolecular dispersing added capable distribution particles; 60 nanometers average particle size 46.3 ITI/g specific surface area much higher than normal powder; high activity free obvious oxidation after being exposed air long time.
