This book was released on 2022-11-08 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: Currently, colour removal dye degradation from synthetic wastewater of RB21 dye using photocatalysis with numerous spinel catalysts created in different methods. The reactive turquoise blue (RB21) dye, which belongs to the phthalocyanine group and has a strong azo link and a Cu2+ metal complex, is a very stable molecule that is difficult to degrade. Textile, paper, and leather sectors all employ reactive dyes. Spinel ferrites are oxides with the general formula AB2O4, where A and B are rare earth, alkali metal, and transition metal cations. Researchers have used spinel catalysts in photocatalytic degradation technology to combat wastewater pollution caused by dyes. The present research is focused on the creation of Magnesium and Cobalt ferrites spinel catalysts for the breakdown of RB21 dye. The most efficient photocatalyst was chosen, and the catalyst dosage, pH, dye concentration, reactor temperature, irradiation time, and other parameters were optimized. In the present work spinel catalysts (CoFe2O4, MgFe2O4, Mg0.5Co0.5Fe2O4, and Ni0.5Co0.5Fe2O4) were prepared by different methods. The operating conditions for spinel synthesis were observed at 146˚C commencing combustion of spinel ferrites. The experiments were performed under varying light sources like a 700W microwave system, and a Visible-Light photocatalytic reactor. The photocatalytic activity was carried out using a light source (two 9W LED bulbs, Halonix) and stirring the sample (400 rpm, 25°C).

This book was released on 2021-02-17 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the public enhanced awareness towards eco-preservation, eco-safety and health concerns, environmentally benign, nontoxic and sustainable bioresource materials produced mainly from non-food crops have revolutionized all industrial sectors particularly textile industry. In recent years, textile industries in developed countries are getting increasing interest in global interest due to the varied and changing world market conditions in terms of price, durability and fiber mixtures as well as design, colors, weight, ease of handling and product safety. The increasing environmental and health concerns owing to the use of large quantities of water and hazardous chemicals in conventional textile finishing processes lead to the design and development of new dyeing strategies and technologies. Effluents produced from these textiles wet processing industries are very diverse in chemical composition, ranging from inorganic finishing agents, surfactants, chlorine compounds, salts, total phosphate to polymers and organic products. This aspect forced western countries to exploit their high technical skills in the advancements of textile materials for high quality technical performances, and development of cleaner production technologies for cost effective and value-added textile materials. Therefore, vast and effective research investigations have been undertaken all over the world to minimize the negative environmental impact of synthetic chemical agents through the sustainable harvest of eco-friendly bioresource materials. The book will discuss following research developments in academic and industry: Improvement in dye extraction and its applications Impact of textile dyeing on environment Textile finishing by natural and ecofriendly means Natural dyes as environmental-friendly bioresource products Textile effluent remediation via physical, chemical and biological processes.
