Abstract: Extraction kinetics of phenol with N, N-di (1-methyl-heptyl)
acetamide-kerosene using hollow fiber membrane extractor has been studied. The
rate regularities and kinetic types of forward and backward extraction were
obtained respectively by determining the forward and backward extraction rate
under various experimental conditions. The mass transfer mechanism was
discussed. Both the forward and backward extraction of phenol might be
controlled by diffusion processes, and the diffusion resistance for both
forward and backward extraction mainly exists in aqueous phase. In addition,
ways to optimize the extraction process of phenol were discussed as well.
