The adsorption of neutral and hydrolyzed polyacrylamides, which are currently used in enhanced oil recovery, on minerals the surfaces of which carry silanol and aluminol groups such as siliceous minerals and akolinite is studied. All experiments are conducted in batch on powdered minerals. The conditions for the elimination of detrimental effects of both mechanical degradation of polymers and flocculation of mineral particles during the batch experiments have been determined, leading to a reliable methodology for the adsorption measurements. The surface sites responsible for adsorption are identified, and a change in surface charge by thermal pretreatment of minerals is found to alter the polymer adsorption accordingly. The two main results thus derived from this study are: a methodology providing reliable and reproducible data, and, the identification of the mechanisms of polymer adsorption and the major parameters governing the process.
