ABSTRACT:
A method of producing iron acetate coated silica sol which comprises the steps of passing a mixture of ion-free colloidal silica and an inorganic iron salt in contact with a strong base anion exchange resin in the acetic acid salt form under conditions whereby the iron salt is converted to the iron acetate and is coated on the silica sol, thereby producing an iron acetate coated silica sol.
