Research on adsorption of phenols in wastewater with cyclodextrin

Study of optimal process conditions of cyclodextrins (CDs) for treating wastewater containing phenol. adsorption time is 240 min, the pH value is 5 - 7, CDS dosage is 4 g/L, initial phenol concentration of 100 mg/L, adsorption temperature of 40 degrees C, the highest absorption efficiency can attainment 42,5 %. In the condition of 30 degrees C, adsorption phenol of wastewater by CDs process accords with the Freundliehadsorption model.
