Abstract:
The method for remediation of heavy metals and halogenated hydrocarbon contaminates from aqueous media comprising,forming a solution of a water soluble salt of Fe in water in the presence of a support material,adding an alkali borohydride to the solution to form a precipitate of zero valent Fe having a siloxane coupling on the support material wherein the precipitate has an average particle size of about 5 nm to about 50 nm, andexposing the support material having the zero valent Fe thereon to an aqueous media having a pH of 5.5 or above and having a contaminate selected from the group consisting of heavy metals and halogenated hydrocarbons to cause any one of the heavy metals and halogenated hydrocarbons to deposit onto the precipitate.
