Dye removal with magnetic graphene nanocomposite through micro reactors

Abstract

Contaminated waste water treatment and clean water scarcity are current challenges acutely in the Asian and African continents. This paper bestows applied co-precipitation technique for the fabrication of Magnetic Graphene Nano-Composites (MGNCs) for water treatment purposes. In this paper, characterization procedures were applied to delineate numerous physical and chemical properties of the synthetic MGNCs and mixing performance for several designed microreactors were determined using the Dushman’s method in comparison to two parallel reactions. The mixing timings for different microreactors at flow rates between 100 and 300 ml/hr were determined. MCNCs were utilised to remove an Acid Blue 25 dye as a pollutant from water at diverse types of microreactors. The comparison between the various microreactors’ performance and mixing time was accomplished. The maximum instantaneous removal capacity of graphene-based nanomaterial was recorded using K.M micro mixer about 68% for 10 ppm dye concentration.
