文摘
- •
Lignin mixture derived from sugarcane bagasse was submitted to acid fractionation.
- •
Low-polydispersity lignin preparations with small nanometric clusters were achieved.
- •
Lignin preparations with high radical scavenging capacity were obtained.
- •
Heterogeneous lignin-enriched stream were upgraded into value-added compounds.
