Ionothermal synthesis method of hierarchical pore AlPO-34 molecular sieve

Abstract

Belonging to the technical field of inorganic material adsorption, the invention discloses an ionothermal synthesis method of a hierarchical pore AlPO-34 molecular sieve. The AlPO-34 zeolite molecularsieve is directly prepared by ionothermal synthesis method. The molecular sieve prepared by the method is uniform in morphology and homogeneous in size, compared with the traditional hierarchical pore molecular sieve synthesis, an additional mesoporous template agent or complex post-treatment operation is not needed, the synthesis method is simple and efficient, and the synthesis steps are simple. The synthesized hierarchical pore AlPO-34 zeolite molecular sieve can be applied to separation of heavy metal ions, shows potential application possibility in the fields of environment and catalysis, and has important and wide application prospects.

Description

technical field [0001] The invention belongs to the technical field of inorganic material adsorption, relates to the synthesis and application of multi-level porous AlPO-34 molecular sieves, and provides a new ionothermal synthesis method for synthesizing multi-level porous AlPO-34 zeolite molecular sieve microspheres through ionic liquids. Background technique [0002] With the rapid development of contemporary industry, industrial wastewater discharged from industrial activities such as mining, textile, printing and dyeing affects the water safety of nearly 80% of the world's population. Therefore, how to deal with many heavy metal ions and organic dyes contained in sewage has become the key point in water treatment research. At present, the main methods of sewage treatment are chemical neutralization method, redox method, biological treatment method, physical adsorption method and so on. Among them, the physical adsorption method has attracted much attention due to its l...

Problems solved by technology

[0006] The above reports have carried out a more detailed study on the adsorption performance and adsorption behavior of multi-level porous aluminum phosphate molecular sieves under different system pollutants, which proves that aluminum phosphate molecular sieves have great application potential in sewage treatment, but it is worth noting that the above-mentioned many The synthesis of hierarchical pore aluminum phosphate molecular sieve materials requires the use of relatively expensive organic templates or pore-forming agents

Moreover, most hierarchical porous aluminum phosphate molecular sieve adsorbents are usually prepared by hydrothermal synthesis in a relatively high self-boosting pressure autoclave, so it will bring non-negligible operational safety issues and equipment safety issues
