文摘
- •
Crosslinked PEI-impregnated sorbents were fabricated by wet-impregnation method.
- •
BDDE with diepoxide was selected as an optimal crosslinker.
- •
Leaching and evaporation of PEI were prevented by the crosslinking of PEI.
- •
The formation of urea was also prohibited with BDDE crosslinking.
- •
BDDE crosslinking of impregnated PEI improved physical and chemical stabilities.
