Fig. 28. (A) Isotherm Cs+ sorption data for K6MS. The solid line represents the fitting of the data with the Langmuir model (qm = 66 ± 4 mg g–1; b = 0.17 ± 0.05 L mg–1, R2 = 0.89). (B) The distribution coefficient Kd for Cs+ ion exchange versus the Na+ : Cs+ molar ratio. (C) The distribution coefficient Kd for Cs+ ion exchange versus the Na+ : Cs+ molar ratio. (D) The logarithm values of the distribution coefficient Kd for Cs+ ion exchange versus the pH.
