摘要/Abstract

摘要： Predispersed solvent extraction (PDSE) is a new method for separating solutes from aqueous
solution by solvent extraction and one which has shown promise for extraction from
extremely dilute solution very efficient and very quick. The use of colloidal liquid
aphrons in predispersed solvent extraction may ameliorate the problems such as emulsion
formation, reduction of interfacial mass transfer and low interfacial mass transfer areas
in solvent extraction process. In present paper, colloidal liquid aphrons are successfully
generated using kerosene as a solvent, tributyl phosphate(TBP) as an extractant, sodium
dodecyl benzene sulphate(SDBS) as surfactant in aqueous phase and Tween-80 in oil phase.
Extraction of phenol from dilute solution was studied by using colloidal liquid aphrons and
colloidal gas aphrons in a semi-batch extraction column. It has been found that the PDSE
process is more suitable for extraction of dilute solutions. It has also been discovered
that the PDSE process has a great advantage over traditional single-stage extraction
process.
