determination of thallium iii ions by Oxidative Hydrolysis of rhodamine hydroxamate
New Journal of Chemistry, 2021Co-Authors: Jae Hoon Yoo, Yu Jeong Lee, Kang Min Lee, Myung Gil Choi, Tae Jung Park, Suk-kyu ChangAbstract:Thallium ions are widely used in chemical and industrial applications but are very toxic. Through this research, a novel dual signaling probe that is based on an Oxidative cleavage reaction is examined. The probe showed selective and sensitive optical signaling behavior toward TI3+ through the Oxidative Hydrolysis of rhodamine–hydroxamate. The probe designed for this study exhibited a distinct colorimetric and fluorescence signaling activity for thallium ions compared to the ions of common metals and oxidants. In particular, the hypochlorous acid response of the probe was successfully suppressed using DMSO as a scavenger. The detection limit for thallium determination was 2.9 × 10−7 M and signaling was concluded within 5 minutes. The exploitation of the probe for the rapid screening of elevated urinary thallium levels due to thallium poisoning using smartphone images was also conducted.

Selective fluorescence signaling of hypochlorite in tap water by Oxidative Hydrolysis of sulfonhydrazone
Sensors and Actuators B: Chemical, 2017Co-Authors: Min Jeoung Cho, Hyein Ryu, Hyo Jin Lee, Suk-kyu ChangAbstract:Abstract A new hypochlorite-selective fluorescence signaling probe based on the sulfonhydrazone of 2-acetyl-6-methoxynaphthalene was investigated. The probe was easily prepared by the simple one-step reaction of 2-acetyl-6-methoxynaphthalene with p -toluenesulfonylhydrazide. The probe exhibited off/on-type fluorescence signaling behavior toward hypochlorite in aqueous solution via hypochlorite-triggered Oxidative Hydrolysis of the sulfonhydrazone to yield strongly fluorescent 2-acetyl-6-methoxynaphthalene. Selective hypochlorite signaling over other common oxidants with a large fluorescence enhancement (76-fold) was possible, with a detection limit of 2.0 × 10 −8 M. Hypochlorite signaling was not affected by the presence of other common metal ions or representative anions. As a practical application, the methoxyacetylnaphthalene sulfonhydrazone probe was used to determine hypochlorite levels in a tap water sample using a standard smartphone as the detection tool.
