Abstract
Ultrasound enhanced Azo Dye adsorption by Graphene Oxide Nanocomposite
Highlights
Alarming proportions of azo dyes present in industrial effluents exert a severe impact on the environment by causing harm to humans and ecosystems adjacent to their point of discharge [1,2]. 7X105 tonnes of dyes are approximately manufactured commercially every year for industrial applications [3]
The present study was performed to investigate the potential of Graphene oxide (GO) – Zinc oxide nanoparticle (ZnO NPs) composites as an inexpensive, convenient and non-toxic adsorbent for removal of Methylene blue (MB) from solution
99.87% removal of upto 120 ppm dye was achieved in 6 min using only 0.75 g L-1 GO-ZnO nanoparticles (ZnO NPs) nanocomposite as adsorbent
Summary
Alarming proportions of azo dyes present in industrial effluents exert a severe impact on the environment by causing harm to humans and ecosystems adjacent to their point of discharge [1,2]. 7X105 tonnes of dyes are approximately manufactured commercially every year for industrial applications [3]. 7X105 tonnes of dyes are approximately manufactured commercially every year for industrial applications [3]. Alarming proportions of azo dyes present in industrial effluents exert a severe impact on the environment by causing harm to humans and ecosystems adjacent to their point of discharge [1,2]. These dyes are reckoned as primary toxicants due to their potentials of causing carcinogenesis and mutagenesis [4]. It has become highly essential to ensure efficient removal azo dyes from effluents bearing them in order to maintain health and safety of the environment [4]. GO sheets tend to aggregate on being suspended in aqueous media rendering the Volume 3 Issue 2 1000120
