Effect of pH
(A), ionic strength (B), selective adsorption (C),
and contact time (D) on and adsorption isotherms for (E) the adsorption
of U(VI) from solution onto PE and PO4/PE, and the related Ce and ln Kd (F). m/V = 0.20 g/L. (A) T = 25 ± 1 °C, I = 0.1 mol/L
NaCl, contact time: 24 h, and C[U(VI)]initial = 50.0 mg/L. (B) T = 25 ± 1 °C, pH =
8.2 ± 0.1, contact time: 24 h, and C[U(VI)]initial = 50.0 mg/L. (C) T = 25 ± 1 °C, pH =
8.2 ± 0.1, I = 0.1 mol/L NaCl, and contact time:
24 h. In (D), T = 25 ± 1 °C, pH = 8.2 ±
0.1, I = 0.1 mol/L NaCl, and C[U(VI)]initial = 50.0 mg/L. (E, F) pH = 8.2 ± 0.1, I = 0.1 mol/L NaCl, and contact time: 24 h.
