From: First-principle calculations of sulfur dioxide adsorption on the Ca-montmorillonite

The change of total DOS in Ca-montmorillonite according to adsorption capacity. (a–f) Represent total DOS for Ca-montmorillonite according to the value of adsorption capacity are 0 mmol g\(^{-1}\), 0.68 mmol g\(^{-1}\), 3.42 mmol g\(^{-1}\), 6.85 mmol g\(^{-1}\), 10.27 mmol g\(^{-1}\), and 13.70 mmol g\(^{-1}\), respectively.
