A rhodamine-based colorimetric sensor, RBOV has been synthesized and modified for selective detection of Cu2+, Ni2+ and Co2+ ions simultaneously in aqueous medium. The difference in color change upon binding with these three cations makes it an interesting multianalyte sensor. Furthermore, the detection limits of RBOV for Cu2+, Ni2+ and Co2+ are down to 4.0 x 10(-2) mu M, 3.2 x 10(-1) mu M and 4.8 x 10(-1) mu M respectively. The possible sensing mechanism analyzed from Benesi-Hildebrand plot, Job's plot, FTIR and DFT studies showed a 1:1 stoichiometry of sensor-metal complex for all three analytes. Practical application of sensor was conducted in real time using test strips and MTT assay was conducted to determine its cytotoxicity. (C) 2021 Elsevier B.V. All rights reserved.
