Enrichment and isolation of phenol from its aqueous solution using foam fractionation

다국어 초록 (Multilingual Abstract)

In this work, the feasibility of foam fractionation for the enrichment and isolation of phenol from itsaqueous solution was studied by using cetyltrimethyl ammonium bromide (CTAB) as the collector. Atwo-stage foam fractionation technology was developed for simultaneously obtaining a high enrichmentratio and a high recovery percentage. Under the suitable operating conditions, the enrichment ratio andrecovery percentage of phenol reached as high as 84.46 and 93.43%, respectively. Subsequently, foamfractionation was also used to isolate phenol from CTAB in the first stage foamate, in which theinteraction between phenol and CTAB could be weakened by adjusting pH. The concentration of CTABsignificantly decreased from 11.230 g/L in the feeding solution to 0.620 g/L in the residual solution byusing the foam fractionation, while the concentration of phenol slightly decreased from 2.533 g/L to2.450 g/L. The results indicated that it was practicable to successively enrich and isolate phenol from itsaqueous solution by using foam fractionation.
