Taking into account that the pH of nuclear waste and contaminated ground water may vary from strongly acidic to extremely alkaline, we have also studied the effect of pH on Sr 2+ adsorption. Sr 2+ ion exchange experiments of KMS-1 with solutions of various pH (1.7–10) indicated significant Sr 2+ uptake in the entire pH range tested ( Fig. 4 A ).
