This research was done for possible treatment of impermeable surfaces rainwater runoff containing heavy metal ions by manganese oxide coated on polypropylene support. Manganese oxide was coated by Birnessite Coating Methods(BCM)and the coating analyzed by SEM and FT-IR techniques. The efficiency of heavy metal ions adsorption was also assessed via both batch and column tests. Adsorption efficiencies of Cd, Zn, Cu, and Pb were 99.4%, 98.9%, 96.7%, and over 95.7%, respectively. The adsorption progress pattern reveals quite fast adsorption at initial periods of treatment and change to slower rates at later times.
