[en] Radiological contaminations are becoming a major concern due to unwanted discharge of nuclear reaction products in the environment. Contamination of drinking water by uranium has documented nephrotoxicity. Therefore, the detection and remediation of radioactive elements is very significant. There are many techniques for the removal of radioactive elements e.g., electrocoagulation, emulsion liquid membrane (ELM), using zero-valent iron, etc., which are often time consuming and involve toxic reagents. Recently, aqueous biphasic systems (ABSs) have shown to offer an environment friendly tool for extractions of several analytes. Here we report the extraction of trace uranium by ABS using morin hydrate as a polyphenolic extractant which forms a strong complex with UO₂²⁺
