Biosorption of sunset yellow and malachite green dyes using mixed fruit peel waste and musa acuminata derived iron oxide nanosorbent

Abstract

Industrial pollutants are gaining attention over the past decade due to water scarcity problems, reckless human activities, global warming, etc. The demand for treatment and disposal of hazardous pollutants might be the foremost importance to combat water scarcity. Therefore, a novel system must be developed to meet the industrial wastewater treatment strategies, considering the basics behind the conventional treatment protocols. Dyes are most prevalently used in the industries such as textiles, pharmaceuticals, food, paper, plastic, printing and leather tanning industries. The presence of dyes in the aqueous environment would affect flora and fauna. Also, it causes numerous health defects in humans, such as kidney failure, respiratory disorders, metabolic dysregulation and sometimes cancerous. Several conventional treatment strategies are in practice for eradicating dye effluent, including flocculation, filtration, coagulation, photodegradation, and advanced oxidation processes. Out of which, adsorption seems to be the best-suited, highly appreciable technique for removing industrial textile dye wastewater due to its salient features, such as being cost-effective, time intensive, user-friendly, and eco-friendly. In recent decades, global researchers developed numerous adsorbents such as activated carbon, charcoal, nanomaterials, biomass as adsorbent, metal oxide nanoparticles and many others. newlineThe current investigation newline
