文摘
- •
High-performance polyimide was used as heavy metal adsorbents.
- •
The contradiction between hydrophilicity and high performance of PI was solved.
- •
Adsorption amount for Cu2+ of PI/silica was 77 times higher than that of PI.
- •
The adsorption ability remained steady for more than 50 recycling processes.
