Introductory overview of polymer adsorption in porous media

1 Introductory overview of polymer adsorption in porous media 

In surveying the literature on polymer adsorption in porous media as it pertains to oil recovery applications, it is evident that the level and nature of polymer adsorption depends mainly on  

In the following two subsections, some of the main features of the adsorption of HPAM and xanthan in porous media will be outlined. It is convenient to separate the discussion of these two polymer types because of their structural differences, as explained earlier in this work. HPAM is a flexible coil polyelectrolyte and, for the reasons discussed previously, shows much more sensitivity to solution conditions, pH, salinity, etc., than xanthan, which has a more rigid molecular structure.
