Abstract

The invention discloses a preparation method of a palladium -cellulose membrane capable of synchronizing emulsion separation and dye degradation, and relates to a preparation method of a palladium- cellulose membrane. The invention aims to solve the problems of performance reduction caused by easy agglomeration of palladium nanoparticles, poor separation performance of the existing oil-water emulsion, and rapid reduction of membrane flux in the use process. The preparation method comprises the following steps: 1, preparing a cellulose membrane; 2, loading palladium particles; and 3, drying. The preparation method is used for preparing the palladium -cellulose membrane capable of synchronously separating the emulsion and degrading the dye.

Description

technical field [0001] The invention relates to a preparation method of palladium-cellulose membrane. Background technique [0002] With the development of technology and industry, toxic organic pollutants pose a threat to the water environment due to their difficulty in removal and degradation. Organic dyes and organic oils are notorious as typical organic pollutants. Recently, many efforts have been made to treat these water bodies containing such pollutants. The conventional physical and chemical methods of adsorption or reverse osmosis to remove organic dyes only involve the phase transfer of pollutants and cannot degrade organic dyes. In contrast, the preferred method for detoxification of organic dyes is in NaBH 4 They are converted into non-toxic compounds by catalytic reduction in the presence of reducing agents. Palladium nanoparticles (PdNPs) have excellent catalytic properties for the reduction of organic dyes. However, the key issues in the nanoparticle form...
