From: Efficient and selective capture of thorium ions by a covalent organic framework

a Effect of pH on removal of Th(IV). b Adsorption kinetics. c and d The distribution coefficients of Th(IV) and competing ions. The inset shows the separation factors of Th(IV) and competing ions. All the error bars represent the standard deviation of the experiments.
