Abstract
The dynamic adsorption and in sity rheological behavior of xanthan biopolymer flowing through porous media have been investigated. Results are related to the depleted layer effect, where polymer/pore wall interaction due to steric hindrance leads to a lower Newtonian apparent viscosity thatn bulk Newtonian viscosity. Previous work on the depleted layer phenomenon has been presented considering the effects of polymer concentration over the very dilute regime, pH and salinity on xanthan rheological and transport behavior in porous media. The results presented in this paper extend some of our earlier findings on the effect od both polymer concentration and salinity on the apparent depleted layer thickness.
