| Abstract: | The extraction of the sorbic acid from wastewater was performed by an ELM process. Various factors in a batch system were studied. The proper composition of the ELM and operational conditions were obtained. The results shown that single-step extraction percentage of sobic acid is over 99%.The mechanism of sobic acid mass transfer was discussed. |
