Several new methods besides the usual organic solvent extraction have been developed over the last few years for the extraction of primary and secondary metabolites. These are: alcohol extraction with various biocompatible solvents, recovery of carboxylic acids and antibiotics with reactive extraction, dissociation extraction, aqueous two-phase extraction, and supercritical and near critical fluid...
In this paper an overview of the developments in liquid membrane extraction of cephalosporin antibiotics has been presented. The principle of reactive extraction via the so-called liquid-liquid ion exchange extraction mechanism can be exploited to develop liquid membrane processes for extraction of cephalosporin antibiotics. The mathematical models that have been used to simulate experimental data...
In this study, cotton and palm kernel seeds have been used to produce biodiesel by reactive extraction in which the biodiesel is produced directly from the particle seeds. This method is influenced by many parameters which include the seeds particle sizes. Hence, the effects of particles sizes on oil content, extraction efficiency of reactive reaction and biodiesel conversion have been investigated...
