文摘
- •
Extraction potential of ultrasound at low temperature of artemisinin is confirmed.
- •
Prolonged ultrasound treatment produces low purity crystals.
- •
Activated charcoal/celite adsorbents are a key to enhance crystal’s purity.
- •
Ultrasound’s diffusion coefficient is seven times higher than conventional one.
