Impact of Ozonation on Decolorization and Mineralization of Azo Dyes: Biodegradability Enhancement, By-Products Formation, Required Energy and Cost

Abstract: In the present study ozonation process was implemented to analyze the effect of ozonation time on the rate of chemical oxygen demand (COD) removal, mineralization and rate of decolorization of azo dyes Three types of azo dyes ie Acid Red 14, Direct Red 28 and Reactive Black 5 were selected Decolorization and mineralization of samples were conducted in batch scale The COD and color removal efficiency were found to be increasing at a certain time of ozonation The results with Acid Red 14, Congo Red and Reactive Black 5 dyes solutions lead to maximum COD reduction of 75%, 67% & 50% respectively 93%, 92% and 94% color removal were achieved after 25 min of ozonation time of the same dyes which highlighted that ozonation process was found to be more efficient for reactive dye decolorization Ozonation by-products analyzed by ion chromatography resulted that it partially mineralized with the formation of chloride, fluoride, sulphate, nitrate and oxalate ions During ozonation process a rapid decrease in p

Isoxazole derivatives as a potential insecticide for managing Callosobruchus chinensis.

Abstract: A series of twenty 3,5-disubstituted isoxazoles were synthesized (using conventional and microwave methods) by the reaction of substituted chalcones with hydroxylamine hydrochloride and characterized by TLC, IR, 1H NMR, 13C NMR spectroscopic data and elemental analysis. The compounds were screened for insecticidal activity against the pulse beetle, Callosobruchus chinensis. Compounds 1a (LC50 36 mg L−1), 1d (LC50 110 mg L−1), 2c (LC50 93 mg L−1) and 5b (LC50134 mg L−1) were more effective than the recommended organophosphorous insecticide dichlorvos (2,2-dichlorovinyl dimethyl phosphate) (LC50 155 mg L−1). These compounds provide a lead for designing new substances endowed with insecticidal activity.
