Nanolayered tin phosphate: a remarkably selective Cs ion sieve for acidic waste solutions†
Abstract
Herein, we report a unique tin phosphate that is remarkably selective to 137Cs+ from extremly acidic solutions because of its special layered structure with an unusually large interlayer space. This acidic exchanger is superior to other existing materials in terms of its selectivity and capacity for 137Cs+ from acidic solutions.
