Synthesis of Highly Sensitivity and Rapid Colorimetric Probe for Hydrogen Sulfide Detection |
초록 |
Hydrogen sulfide (H2S) is a colorless, odorous, and toxic gas generated as a by-product in many industrial processes. Owing to the rapid rise in healthcare concerns, the detection of harmful H2S gas for environmental monitoring has grown importance in industry. In this study, a new colorimetric sensor (IID-C8-2Br) based on the Isoindigo moiety for detection hydrogen sulfide (H2S) has been developed. We investigated changes in the UV-vis absorption spectrum expose to H2S. The spectra results revealed the probe to be highly sensitive (limit of detection: 1.8 μM), rapid (detection time<60 s). Upon the addition of H2S, the intensity of the main absorption band gradually decreased with change in color from red to colorless. In our case, the IID-C8-2Br coated paper strips exhibited color difference (ΔEab = 21.4) upon sensing H2S, that were perceptible with the naked eye, which shows applicability of probe to simple, low-cost, and practical H2S sensors. |
