Adsorption of Organic Dyes by TiO₂@Yeast-Carbon Composite Microspheres and Their In Situ Regeneration Evaluation

Figure 6

Comparison of Langmuir, Freundlich, Temkin, and Koble-Corrigan isotherm models for MB adsorption onto TiO₂@yeast-carbon composites (adsorbent = 0.014 g; solution volume = 100 mL; pH = 6; contact time = 1.5 h; temperature = 298 K; and concentration of MB = 1.0, 2.0, 3.0, 4.0, and 5.0 mg/L, resp.).
