Extraction of Phenylalanine from Dilute-Solutions by Rotating Film Pertraction
The pertraction of phenylalanine in a rotating film contactor was studied, using a solution of di-2-ethylexyl phosphoric acid in n-paraffins as membrane liquid. The RF-pertraction ofphenylalanine from dilute aqueous solutions was a stable continuous process, suitable for selective recovery and concentration of this amino acid. The influence of the principal process parameters was studied and the optimal operation conditions determined.
