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.

Enhancing the renewable energy payback period of a photovoltaic power generation system by water flow cooling

“…As one of the most popular kinds of renewable energies, solar energy is predicted to play a serious role in the future [40]. However, the concepts of carbon capture-storage and progressive technologies of quantum-dot and organic solar cells and new materials [41,42] are going to speed up the notion of GEB [43]. Still, using PV modules offers a number of huge benefits that makes it favorable worldwide.…”

Daylighting, artificial electric lighting, solar heat gain, and space-heating energy performance analyses of electrochromic argon gas-filled smart windows retrofitted to the building

“…The solar thermal collectors on residential buildings also produce waste heat [31,32] that can be harnessed using thermoelectric [33][34][35], and with PV [36], the use of the water-cooling method is still attractive in the hot-arid humid climate. A new development in nanocomposites [37,38] can improve vacuum sealed solar thermal collectors' performance. In the current need, the electric vehicles [39][40][41] and its development of the charging station integrated into a residential building with fast charging algorithms [42][43][44] are also being explored where thermal heat management of the batteries would be required.…”
