Type: article
Abstract: 1, 4 dioxane predominantly found in industrial effluents and air force plants, is of great concern worldwide due to its toxic and carcinogenic nature. Currently, there are limited research on 1,4 dioxane sensors and most of these sensors are intricate metal oxide composites. This study reports the fabrication of novel inherently electroactive graphene oxide nanosheets derived from a natural polyphenolic compound, and the process parameters were statistically optimized using TOPSIS based Taguchi L9 orthogonal array. The proposed novel sensor was employed in the linear range (0.1µM to 3µM) that conforms with the WHO guideline (0.56 µM) for dioxane in water, showed good sensitivity (117 nAnM-1 cm-2 ), detection limit (20.51 nM) and quantification limit (62.16 nM) which is far superior compared to the reported literature on dioxane sensing systems.
