specific Embodiment approach 1

[0028] Specific embodiment one: a kind of preparation method of the palladium-wood film that can synchronize oil-water separation and dyestuff degradation in this embodiment, it is carried out according to the following steps:

[0029] 1. Preparation of pretreated raw materials:

[0030] Immerse the wood chips into the mixed solution, and heat them for 4h-8h at a temperature of 40°C-80°C to obtain the pretreated raw material;

[0031] The thickness of the wood chip is 1mm~10mm;

[0032] The mixed solution is obtained by mixing choline chloride and oxalic acid and heating and melting at a temperature of 40°C to 80°C; the mass ratio of the choline chloride to oxalic acid is 1:(1~5) ;

[0033] 2. Loaded palladium particles:

[0034] cleaning the pretreated raw material, then immersing the cleaned raw material in an aqueous palladium source solution, and heating at a temperature of 40°C to 80°C for 4h to 8h to obtain a wood film loaded with palladium particles;

[0035] The ma...

specific Embodiment approach 2

[0046] Embodiment 2: This embodiment differs from Embodiment 1 in that the palladium source aqueous solution described in step 2 is an aqueous palladium chloride solution. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0047] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that the drying described in Step 3 is standing and drying at room temperature. Others are the same as in the first or second embodiment.

Abstract

The invention discloses a preparation method of a palladium wood film capable of synchronously carrying out oil-water separation and dye degradation, and relates to a preparation method of a palladium-wood film. According to the invention, the problems that the membrane flux is reduced due to the fact that hydrophilic membrane pores are easily blocked by greasy dirt, and an oil-water separation membrane and an oil absorption material can only physically adsorb limited dyes and cannot degrade the dyes are solved. The preparation method comprises the following steps: 1, preparing pretreated rawmaterials; 2, loading palladium particles; and 3, drying. The preparation method is used for preparing the palladium-wood film capable of synchronously carrying out oil-water separation and dye degradation.

Description

technical field [0001] The invention relates to a preparation method of a palladium-wood film. Background technique [0002] In the production process of industries such as oil extraction, petrochemical, leather, textile, food and medicine, a large amount of oily and dyed wastewater will be produced. In order to reduce costs, these oily and dyed wastewater are directly discharged into the water body. At present, the methods for treating oily sewage mainly include physical, chemical and biological methods. Most of these wastewaters contain dyes, and general oil-water separation membranes and oil-absorbing materials can only physically absorb limited dyes and cannot degrade dyes. Many new materials are used to deal with oil-water mixtures and face cost problems, which makes it impossible to solve the application problems at the root. In order to avoid secondary pollution to the environment, people are increasingly inclined to use environmentally compatible substances as raw ...
