Web30 sep. 2013 · Ion exchange and geochemical reactions have been experimentally found to be important in oil mobilization due to enhanced water spreading at low salinity. To evaluate the significance of this surface wetting mechanism, a comprehensive ion exchange model with geochemical processes has been developed and coupled to the multi-phase multi … WebThe difference is in the functional groups on the SPE phase and their charge state. The strong ion exchange phases are called “strong” because the sulfonate cation or quaternary ammonium anion exchange group remain charged over the entire pH range. They are always positively or negatively charged, regardless of pH conditions.
