The invention provides a copper oxide/carboxymethyl cellulose gel modified composite film, and a making method and a use thereof. The making method comprises the following steps: washing and drying a copper net; cutting the dried copper net, carrying out high temperature calcination on the cut copper net in a tubular furnace, naturally cooling the calcined copper net to room temperature, and taking out the naturally cooled copper net; impregnating the calcined copper net in a carboxymethylcellulose sodium solution for a period of time, taking out the impregnated copper net, and impregnating the copper net in a Fe<3+> solution; and taking out the copper net a period of time later, placing the impregnating copper net in an oven, drying the copper net at a certain temperature for a period of time, continuously repeating the above impregnating operation to make the copper oxide/carboxymethyl cellulose gel modified composite film, and preserving the copper oxide/carboxymethyl cellulose gel modified composite film in water. The CuO-CMC modified composite film is produced through the method for high temperature calcination of the copper net and coating of the surface with an organic layer. The making method has the advantages of simplicity in operation, obvious separation effect and high practical values.
