Mechanism unravelling for ultrafast and selective 99TcO4− uptake by a radiation-resistant cationic covalent organic framework: a combined radiological experiment and molecular dynamics simulation study

Separation of TcO4– by a cationic covalent organic framework is achieved for the first time, showing advantages of extremely fast sorption kinetics, ultrahigh uptake capacity, good anion-exchange selectivity, and excellent radiation resistance.

Anion recovery from water by cross-linked cationic surfactant nanoparticles across dialysis membranes

Ion exchange selectivity coefficients for a new cross-linked micellar nanoparticle are reported and are used to predict specific ion recovery (e.g., phosphate) across dialysis membranes.
