文摘

Solid phase extraction was used to recover phenolic compounds from olive mill wastewater. Activated carbon adsorbed 87% of total phenols versus 67–75% for triamine-grafted mesoporous silicas. Quantitative adsorption and recovery of hydroxytyrosol was achieved over triamine-grafted SBA-15. The adsorption performance did not change over adsorption–regeneration cycling.
