Cationic Covalent Organic Nanosheets for Rapid and Selective Capture of Perrhenate: An Analogue of Radioactive Pertechnetate from Aqueous Solution
Abstract
Capture of radioactive TcO 4 – from nuclear wastes is extremely desirable for waste disposal and environmental restoration. Here, we report the synthesis of hydrolytically stable cationic covalent organic nanosheets (iCON) for efficient uptake of ReO 4 –, a nonradioactive surrogate of TcO 4 – . The iCON combines cationic guanidine-based knots with hydroxyl anchored neutral edge units and chloride ions loosely bonded in the pores, rendering extremely fast exchange kinetics toward ReO 4 – with high uptake capacity of 437 mg g –1 and prominent distribution coefficient of 5.0 × 10 5 . The removal efficiency remains stable over a pH range of 3–12 and allows selective capture of ReO 4 – in the presence of excessive competing anions such as NO 3 –, CO 3 2–, PO 4 3– and SO 4 2– with good removal efficiency for ReO 4 – in a simulated Hanford LAW Melter Recycle Stream. Anion exchange between the ReO 4 – in solution and the chloride ion in iCON plays dominant role in the adsorption of ReO 4 – . The iCON shows promise for effective removal of radioactive 99 Tc from nuclear waste.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
