Rhodamine B conjugate for rapid colorimetric and fluorimetric detection of aluminium and tin ions and its application in aqueous media

Recent advances in tin ion detection using fluorometric and colorimetric chemosensors

“…6). 94 Upon incremental addition of Sn 2+ and Al 3+ to a solution of probe 21 in 30% acetonitrile solution, the absorption band increased gradually at 563 nm. This optical behaviour change was related to a change in colour from colorless to pink that could be seen by the naked eye.…”

A Multimode Optical Sensor for Selective and Sensitive Detection of Harmful Heavy Metal Cr(VI) in Fresh Water and Sea Water

“…37 As can be seen from line c in Figures 2C and S5, the appearance of carbonyl peak of the amide group at 1613 cm −1 proved the successful synthesis of RBH. 43 Compared with bare UiO-66-NH 2 , not only the carbonyl peak of amide appeared at 1613 cm −1 but also the strong peaks at 1116 and 1687 cm −1 corresponding to the tensile vibration of C−O−C and C�N + could be observed in the spectrum of UiO-66-NH 2 @RBH, respectively (line e in Figures 2c and S5), 44,45 which proved that RBH has been successfully loaded by UiO-66-NH 2 . The above results were further confirmed by the UV spectra.…”

A Naphthol and Nitroaniline‐Based Dual‐target Chemosensorfor Fluorometric Sensing of Al3+ and Colorimetric Sensing of Fe3+

“…Aluminum is plenty in the earth's crust [1] and is widely used in various fields like medical purposes, the manufacturing industry, food additives, and packing materials. [2][3][4] However, aluminum accumulated in excess in the body causes diseases such as mild depression, Parkinson's disease, fatigue, memory loss, and Alzheimer's disease. [5][6][7] Therefore, it is needed to develop analytical tools that selectively sense Al 3 + ion.…”
