| Abstract: | Fractional dispersed phase hold-up and dispersed side overall mass transfer coefficient for bvine serum albumin were measured in a 0.057m i.d.packed extraction column using a phosphate-polyethylene glycol 4000 system.Raschig rings and structured packing were used as packings.The effect of phase composition on mass transfer process was also studied. |

| Keywords: | aqueous two-phase system continuous counter-current extraction mass transfer coefficient packed column coefficient packed column |
