The article conveys some information:
The colorimetric sensor is a facile, cost-effective, and non-power-operated green energy material for gas detection. In this study, the colorimetric sensing property of a meta-aramid/dye 3 nanofiber sensor for ammonia (NH3) gas detection was investigated. This colorimetric sensor was prepared using various dye 3 concentrations via electrospinning. Morphol., thermal, structural, and mech. analyses of the sensor were carried out by field-emission SEM, thermogravimetric anal., Fourier-transform IR spectroscopy, and a universal testing machine, resp. A homemade computer color matching machine connected with a gas flow device characterized the response of the meta-aramid/dye 3 nanofiber colorimetric sensor to various exposure levels of NH3 gas. From the results, we confirmed that this colorimetric green energy sensor could detect ammonia gas in the concentration of 1-10 ppm with a sensing response time of 10 s at room temperature After washing with laundry detergent for 30 min, the colorimetric sensors still exhibited sensing property and reversibility.2-Hydroxy-4-methoxybenzaldehyde(cas: 673-22-3Synthetic Route of C8H8O3) was used in this study.
2-Hydroxy-4-methoxybenzaldehyde(cas: 673-22-3) is the main component of root bark essential oil of Periploca sepium Bunge. It is a potential tyrosinase inhibitor present in African medicinal plants. 2-Hydroxy-4-methoxybenzaldehyde was used in the synthesis of Schiff base ligand.Synthetic Route of C8H8O3
