Embodiment 1

[0024] Embodiment 1 (raw material corresponding to embodiment 1 in the comparison table and the proportioning value thereof by weight) is carried out in three steps:

[0025] (1) Dissolve 5 parts by weight of 5-hydroxyisophthalic acid and 2.2 parts by weight of sodium hydroxide in 250 parts by weight of water at 75°C;

[0026] (2) Dissolving 2.4 parts by weight of aluminum sulfate in 50 parts by weight of normal temperature water;

[0027] (3) Slowly add the solution obtained in step (2) to the solution obtained in step (1), stir while adding, continue to react for 2 hours after the addition, filter with suction, wash with water, and dry at 160°C to obtain Hierarchical structure of pore coordination polymer adsorption materials.

[0028] For the rest of Examples 2-7, respectively compare the raw materials and their weight ratios of the corresponding examples in the above table, and use the same method as Example 1 to produce a mixture of mesopores and macropores in ...

Abstract

The invention discloses a method for producing a hierarchically structured porous coordination polymer absorbent material, which comprises three steps of 1, dissolving aromatic carboxylic acid in an alkaline solution of 60 to 90 DEG C; 2, preparing a brine solution with metal ions; and 3, slowly adding the solution obtained in step 1 into the solution obtained in step 2, continuously reacting for1 to 8 hours, suction filtering and drying after washing the mixed solution by water and then obtaining the hierarchically structured porous coordination polymer absorbent material. The coordination polymer absorbent material has mesoporous and macropores at the same time; and the aperture is 2 to 150 nanometers. The mesoporous/macropore coordination polymer absorbent material produced by the method has well application prospect in the areas of environment pollution, chromatograph, catalysis and the like; the product is dried at a high temperature of 120 to 160 DEG C and has a relatively highheat stability. The production method is good for the environment, simple and easy for implementation and low in cost.

Description

Technical field [0001] The present invention involves a production method for adsorbing agents applied to sewage purification, which is specifically to produce the production method of the coated polymer adsorption material of the grade structure. Background technique [0002] In recent years, due to the needs of basic research and production, the research and development of various sizes of grade medium / large -hole materials has attracted widespread interest.The medium material with a large -hole structure with a catalyst and adsorbent has become a hotspot of research. This type of division -grade medium / large -hole material has the advantages of the medium materials and large hole materials.The large holes in the holes / large holes help the spread of the reactor and products, improve the transmission of substances, eliminate the limit of the pore diameter, and obtain the diffusion of greater advantages than a single hole.It is these advantages that have determined that the grade...
