The Langmuir model fitted well the adsorption isotherms of lipase on the hydrophobic resin. The model parameters, Qm and kd, were affected by NaCl concentration: Qm increased from 31 to 80 U g-1 resin, and kd changed from 9.4 to 3 U ml-1. Column modelling and the simulation data were compared with the experimental data with good agreement. The highest achieved column efficiency was 71%.
