A kind of covalent organic framework film of staggered stacking and its preparation method and application

PendingCN122273333AApplies to selective transmissionHighly selective ion screeningRadioactive wasteMesitylene
This invention relates to a staggered covalent organic framework thin film, its preparation method, and its application, belonging to the field of thin film technology. The invention first dissolves an amine monomer in acetic acid solution to obtain an aqueous solution; then dissolves an aldehyde monomer in mesitylene to obtain an organic solution; finally, the aqueous and organic solutions are added to the aqueous and organic phase chambers of a diffusion cell, respectively, for interfacial polymerization. After the reaction, the membrane material is removed, washed, and dried to obtain the staggered covalent organic framework thin film. This film forms a staggered stacked structure and constructs sub-nanometer transport channels with pore sizes of approximately 0.5 nm to 0.7 nm. Through a synergistic mechanism of Donnan repulsion and hydrogen bonding interactions, it maintains structural stability under extreme environments of high acidity, strong corrosion, and high radiation, achieving highly efficient selective permeation of protons and efficient retention of metal ions in high-level radioactive waste liquids.

Method for removing acid from flue gas of waste incineration power plant based on caustic soda white mud

ActiveCN117695834BTo achieve the purpose of deacidificationHigh specific surface areaFlue gasSlurry
This invention relates to a method for deacidification of flue gas from waste incineration power plants based on alkali-based white mud. The method involves mixing alkali-based white mud and wet deacidification waste liquid to form a slurry, which is then sieved to remove large particles, yielding a deacidification agent slurry. The alkali-based white mud in the slurry has a solid content of 15-25%. The alkali-based white mud has a pH of 10-12 and, by mass percentage (dry basis), comprises 70-90% CaO, 5-20% MgO, 1-3% SiO2, and 1-5% Al2O3. The deacidifying agent slurry is prepared by adding 0.5-1% Fe2O3, 0.3-2% Na2O, 0.5-3% chloride, and 0.5-5% SO3 to a spray drying tower in a semi-dry flue gas deacidification system. After atomization, it is sprayed into the flue to react with acidic gases in the flue gas of the waste incineration power plant to remove HCl and SO2. This method can achieve a HCl removal rate of up to 90% and a SO2 removal rate of up to 80%. It is a low-cost and effective method of "treating waste with waste".
