- Conclusion -
This invention targets filtration and adsorption scenarios in laboratories and daily‑life settings. Inspired by human pulmonary respiration and oxygen‑exchange mechanisms, a multi‑functional filtration device based on the bionic alveolus model is developed. Equipped with replaceable filter media, it can adsorb and filter various substances.
Experiments show that compared with conventional static filter materials, this device maintains optimal adsorption performance continuously. It improves filter‑material utilization while delivering stable filtration outcomes.
Thanks to its modular design, the device features great expandability. Further optimization will be conducted to verify its applicability across diverse fields.
Project Overview
- Background -
As the concentration of citric acid increases, more abundant pores will be constructed as more esterification is taking place.
Therefore, more TiO2 will be loaded and a higher proportion of methylene blue in the solution will be degraded and absorbed.
