The paper prepared a nanoscale hydrated ferric oxide loaded activated carbon by co-precipitation procedure so as to study its adsorption capacity to lead and structure variation of activated carbon before and after loading and also carried out TEM and XRD characterized analysis.It used dynamic small column test to study the effect of pH, feed concentrations and empty bed contact time on activated carbon's adsorption capacity to lead, and prepared breakthrough curves of unloaded and loaded activated carbon in natural river water. Results indicated that amorphous nanoscale hydrated ferric oxide can be successfully loaded in activated carbon which can improve the adsorption capacity of activate carbon for lead after loaded. The adsorptive capacity increases with the increase of pH and empty bed contact time.In addition, the water concentration does not affect the adsorption capacity of lead.The paper took natural river water as treatment object and got the result that the operational bed volume of activated carbon at breakthrough point before and after loaded are 1233 and 11004 respectively and increased by 9 times.The study showed that amorphous nanoscale hydrated ferric oxide loaded activated carbon can effectively remove lead in actual wastewater and the method has good application prospect.
