In environtment protection field, it is one of key controlling objects to decontaminate phenol wastewater, which poses great harm to environment and becomes a serious problem in metallurgy industry. Photocatalytic oxidation of water contaminants is a new method for wastewater treatment. It is widely and deeply studied by researchers for its high photo degradation efficiency, none secondary pollution caused and the potential of utilitilization of solar energy. Therefore, preparation of effective laden photoc...
