Surfactant Adsorption Isotherms: A Review

🤖 Plain-English Summary

The need to minimize surfactant adsorption on rock surfaces has been a challenge for surfactant-based, chemical-enhanced oil recovery (cEOR) techniques. Some more complex adsorption isotherms are also discussed in this paper, such as Redlich-Peterson and Sips isotherms, both involve three parameters.

🔑 Key Findings

• Modeling of adsorption experimental data is very useful in estimating the extent of adsorption and, hence, optimizing the process.
• This paper presents a mini-review of surfactant adsorption isotherms, focusing on theories of adsorption and the most frequently used adsorption isotherm models.
• Two-step and four-region adsorption theories are well-known, with the former representing adsorption in two steps, while the latter distinguishes four regions in the adsorption isotherm.
