Since the ecological and environmental monitoring and protection has been widely addressed and emphasized by academic research and public, the remediation and removal for the pollutants became a critical subject for the Industry, Official and Academy. The state-of-the art technology needs to be comprehensively surveyed covering a wide spectrum of related areas. This book is aimed to fulfill this goal and hopefully will benefit the student, teaching staff, engineers, staffs in the civil corporation and also the public.
This book is divided into 5 chapters and an introduction. In the introduction section, Nitrogen compounds and their toxicity and pollution in the water environment are first addressed and the necessity to remove them from the water body is emphasized. Chapter 1 discusses conventional method and technology of Nitrogen removal from water. Chapter 2 covers conventional Biological method for nitrogen removal. The next three chapters are the essence of this book and maybe the most interesting parts for the readers, in Chapter 3 the authors introduce food industry wastewater treatment from nitrogen compounds. In Chapters 4 and 5 a new approach towards environmental pollution remediation biotechnology by different types of Bio Electrochemical Systems (BES) is presented. The authors exert our effort to make this book as an important reference and manual guide for the readers interested in the field. Read out the full version here.
Journal: Current Organic Synthesis
Author(s): Navjeet Kaur
Background: Chemists have been interested in light as an energy source to induce chemical reactions since the beginning of scientific chemistry. The organic photochemical reactions do not require toxic or polluting reagents so these reactions presented perspectives in the context of green chemistry and sustainable processes.
Objective: The largest classical divisions of organic chemistry are constituted by heterocycles. The role of heterocyclic compounds in a number of areas cannot be ignored. That’s why the chemists are continuously trying to design and synthesize heterocycles. This review summarizes the chemistry of photochemical reactions with emphasis on their synthetic applications. In this review, the most important photochemical transformations that have been employed in six-membered N-heterocycles synthesis are presented.
Conclusion: This review discussed the research activities in organic photochemistry that are applicable in organic synthesis. This review outlined the synthesis of heterocyclic compounds. Traditional approaches require highly specialized or expensive equipment, are highly inconvenient, or would be of limited use to the synthetic organic chemist. Therefore, these have been omitted by them. Photochemistry can be used to prepare a number of heterocycles selectively, efficiently and in high yield.
