Manufacture Of Low Grade Zeolites From Fly Ash For Fertiliser Applications

This book discusses different aspects of energy consumption and environmental pollution, describing in detail the various pollutants resulting from the utilization of natural resources and their control techniques. It discusses diagnostic techniques in a simple and easy-to-understand manner. It will be useful for engineers, agriculturists, environmentalists, ecologists and policy makers involved in area of pollutants from energy, environmental safety, and health sectors.

This book presents a thorough review of the state-of-knowledge and recent innovations in the synthesis of pure and improved grades of fly ash zeolites (FAZ). Addressing improvements to conventional methods, it also showcases a novel technique for the synthesis of high cation exchangers from fly ash and detailed characterization techniques for the products obtained. In addition, it examines in detail various areas of specific applications of fly ash zeolites. Over the years, several methods such as hydrothermal, fusion prior to hydrothermal, microwave assisted hydrothermal and molten salt techniques for producing FAZ have been developed. However, one-step and two-step reactions between the fly ash and alkali usually generate alkaline wastes that may cause environmental contamination. In addition, the separation of FAZ from the partially activated fly ash (the impurities) remains a major concern for researchers and industrialists alike. /divIn view of these challenges, this book presents a novel technique for three-step activation (TSA), which focuses on recycling the fly ash-NaOH-water reaction by-products until zeolitic residue is formed. The FAZ (the final residue after third step reactions) synthesized in this manner exhibits exceptionally high cation exchange capacity, specific surface area and pore area. This book offers a comprehensive compendium of reading material on fly ash and its recycled product, the zeolites. Students at both undergraduate and graduate levels, researchers, and practicing engineers will all find this book to be a valuable guide in their respective fields.

Nanofertilizer Delivery, Effects and Application Methods explores the science of nutrient nanoformulation, a potential tool toward sustainable and climate-sensitive crops.Wide-spread use of chemical fertilizers has been shown to causes significant damage to soil structure, mineral cycles, soil microbial flora, plants, and creating human health risk both immediately and for future generations. Through methods that include targeted distribution, and gradual or controlled release, nanostructured fertilizers can improve nutrient usage efficiency. According to recent studies, through environmental cues and biological demands, nano-fertilizers can respond to specifical challenges, and boost agricultural yield by increasing the rate of seed germination, seedling growth, photosynthetic activity, nitrogen metabolism, and carbohydrate and protein synthesis. Nanofertilizer Delivery, Effects and Application Methods discusses the potential agricultural benefits of nanofertilizers from coverage of their formulation and delivery, to application, plant uptake, translocation, and destiny, and their overall effect on plant physiology and metabolism. This book is ideal for researchers in industry and academia. Highlights types, uses, and advantages of a wide range and variety of nanofertilizers on agri-food sectors Looks at current practices, their challenges, and future development opportunities Includes methods and applications for real-world insights

This book collects recent results about research activities on zeolites, from synthesis to application. It is composed of two sections. The first is devoted to articles and brief review articles on the synthesis of zeolite from fly ash and final application of these newly formed minerals to solve environmental problems. The second part of the book provides useful information on different applications both of natural and synthetic zeolites ranging from environmental pollution to industrial and commercial applications. The performance of zeolite molecular sieves, hollow titanium zeolites and luminescent zeolites is interesting considering the new frontiers reached by the research on zeolites. This book is a useful instrument for researchers, teachers and students who are interested in investigating innovative aspects of the studies on zeolite.
