Abstract Lactoferrin is a protein that is present in cheese whey (a waste product from the dairy industry) and has several biological activities. However, its production from whey must have a high yield and low cost for industrial applications. As such, this study reports the use of polyacrylamide cryogel, loaded with Cu(2+) (through the bond with iminodiacetic acid (IDA)), as an adsorbent for the chromatographic process to capture lactoferrin whey. Ultrafiltered cheese whey was passed through the cryogel-IDA-Cu(2+) system. The eluates were subjected to analysis of total protein, SDS-PAGE and size exclusion chromatography. The results showed an axial dispersion coefficients, at different superficial velocities of liquid, in a range of 10(-6)-10(-5)m(2)/s. The cryogel demonstrated good hydraulic permeability (4.7086×10(-13)m(2)) and a porosity of approximately 78.2\%. The IDA-Cu(2+) cryogel system was also able to capture lactoferrin in high purity.
