Current strategies for visual detection of uranyl ion (UO2+2) often require DNAzymes and organophosphorus receptors as well as various nanomaterials that may affect the selectivity, sensitivity, and accuracy in a complicated environment. Here, we circumvent these drawbacks by introducing a formic acid (FA)-assisted photolysis of UO2+2 initiated chromogenic reaction for specific recognition element-free colorimetric detection of UO2+2. The colorless 2, 2â?azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS) is oxidized by the superoxide anion from the photolysis of UO2+2 to generate green ABTS radical, which enables the determination of UO2+2 at a concentration of 0.5 μM with the naked eye. The present colorimetric assay is able to determine concentrations of UO2+2 from 0.1 to 100 μM, with a limit of detection as low as 0.01 μM. Impressively, the specific recognition element-free colorimetric assay possesses excellent selectivity over common inoganic ions with even 50-fold higher concentration than UO2+2. In addition to good sensitivity and selectivity, this colorimetric assay is also capable of determining UO2+2 in natural water samples with satisfactory recoveries.
