文摘
- •
Characteristics of WEOM from the four composting treatments were investigated.
- •
Penicillin degradation occurs mainly in the first 12 days.
- •
A 5-component model was successfully obtained with EEMs-PARAFAC.
- •
Components 4 and 5 are perfectly adequate for monitoring organic transformation.
- •
EEMs-PARAFAC is proposed to evaluate stability during composting of PMD.
