  • Patent number: 8083950
    Abstract: The present invention relates to a method for recovering an organic-inorganic element-doped metal oxide from a hydrolysable metal compound, accompanied with contaminated water treatment. The present invention comprises steps of: a) adding a hydrolysable metal compound as a coagulant to a contaminated water to form a separable floc between the hydrolysable metal compound and contaminants present in contaminated water; b) separating the separable floc and the pre-treated water after flocculation treatment; and c) calcinating the separated floc over 500° C. to produce an organic-inorganic element-doped metal oxide. More preferably, the present invention further comprises subjecting the pre-treated water of the step b) to a microwave treatment to cause a photocatalytic degradation of an organic contaminant that remains in the pre-treated water, with the assistance of the remaining hydrolysable metal compound.
