- •
Ultrasonic treatment was able to sonochemically modify molecular structure and reactivity of enzymatic hydrolysis lignin.
- •
The effect of ultrasound on the amount of phenolic hydroxyl groups on lignin varied with the ultrasonic power and treatment time.
- •
Phenolic hydroxyl group, antioxidant activity, and reactivity of lignin significantly increased after treatment.
- •
Ultrasound treatment showed promise for improving lignin chemical reactivity.
