Kinetic Region | Time Range (min) | √t Range (min0.5) | kid (\(\:mg/g.{min}^{0.5}\)) | Intercept (mg/g) | R² Value | Dominant Mechanism |
|---|---|---|---|---|---|---|
Region I | 0–20 | 2.24–4.47 | 53.5 ± 2.1 | −7.5 ± 1.2 | 0.99 | External mass transfer |
Region II | 20–60 | 4.47–7.75 | 32.6 ± 1.8 | 80.7 ± 3.5 | 0.98 | Intraparticle diffusion |
Region III | 60–120 | 7.75-10.00 | 19.5 ± 1.2 | 249.5 ± 5.8 | 0.95 | Equilibrium attainment |
