In this thesis, an experimental investigation was conducted to compare the performance of the continuous pH-parametric pumping and the pH-cycling zone adsorption process on protein separation.

The model system studied was hemoglobin-water. on CM-Sepharose CL-6B (cation) exchanger in a single-column system. Various modes of operation were tried on both the pH-parametric pumping and the pH-cycling zone adsorption method. The separation factors for each mode of operation were computed and compared.

It is shown that the continuous pH-parametric pumping, with circulation to insure the pH uniformity inside the column, has the better separation factor than the pH-cycling zone adsorption method.
