Green Adsorbents To Remove Metals Dyes And Boron From Polluted Water

This book reviews adsorption techniques to clean wastewater, with focus on pollution by dyes and heavy metals. Advanced adsorbents include carbon nanomaterials, biomass, cellulose, polymers, clay, composites and chelating materials.

Adsorption technology is a promising avenue for wastewater treatment. Numerous adsorbent materials are presently synthesized. Green or environmental friendly adsorbents are derived from plants and agricultural crop sources, giving them a very low production cost when compared to synthetic polymers. This monograph explains the basic principles of green adsorption technology, their production processes and strategies to remove different categories of environmental pollutants (dyes, heavy metals and phenols/pesticides). The book explains details in terms of features such as adsorption capacity, physico-chemical kinetics and reuse potential. A summary of the economics and future prospect for green adsorption technology is also given. This text is a handy reference for environmental chemistry students, researchers and policy makers.

Separations of Water Pollutants with Nanotechnology, the latest volume in the Separation Science and Technology series, offers new solutions for remediating water pollution utilizing nanomaterials with separation methods. Current water purification methods are unsuitable, inconvenient or expensive, so there is a need for new and better processes and techniques. Nanomaterials can purify water by removing pollutants such as heavy metals, pathogens, organic compounds, inorganic compounds, pharmaceuticals, and chemicals of emerging concern. These can effectively replace membrane-based methods if the right expertise is developed—this book helps separation scientists do just that. Existing water treatment problems can be solved by applying a nanotechnology-based processes: antimicrobial nanotechnology, zero-valent iron nanoparticles, nanoadsorbents, nano-enhanced membranes, nanometal oxides, and nano photocatalysts. The current literature places emphasis on materials chemistry rather than the separation methods used for water purification. This new volume presents a collection of chapters that deal with remediation based on separation chemistry. Written by leaders in their respective fields from around the world and edited by Satinder Ahuja, a leading expert on water quality improvement Covers the environmental impact of anthropogenic nanoparticles and plant derived bionanomaterials, which are not contained in other books related to nanomaterials for water purification Illustrates key information visually wherever possible throughout the book, e.g. process diagrams in the nanomaterial synthesis and nanomembrane fabrication chapters, electron microscope images, and more

This book covers the various aspects of nanohybrid materials and its composites for their application in treatment of toxic textiles dyes for cleaning the environment especially water and wastewater. The book first looks into the various preparation and characterization techniques for nanohybrid materials. The replacement of other conventional materials with highly efficient (high surface area, pore size, and chemical and mechanical strength) nanohybrid materials and their application in the field of environmental purification through treatment of textile dyes is highlighted in the later part of the book. The book caters to students, researchers, and scientists who are working in the field of wastewater treatment for incorporating novel materials to remove toxic textile dyes from contaminated wastewater.

Water covers 70% of the Earth, but only 3% of it is drinkable, and most of this water (2%) is not accessible because it is locked in ice caps, glaciers, or the soil. Globally, 2.7 billion people experience water scarcity for at least one month of the year, while around 1.1 billion people lack access to water. In this book, scientists and entrepreneurs from the five continents present their ultimate expertise to address the crisis. The book comprises twelve chapters that present case studies from different parts of the world and industrial products for water purification, desalination, and energy production.

Various physico-chemical approaches for the removal of toxic pollutants are available, but these are not very effective. Biological approaches using microorganisms, green plants or their enzymes to degrade/detoxify contaminants are eco-friendly and low cost. This book provides a comprehensive overview of contaminants, their toxicity, and eco-friendly approaches for their management by cost effective sustainable methods.

This book focuses on the biologically derived adsorbent with numerous applications in wastewater treatment, metal recovery, biosensor development, and so forth. It initiates with the description of biological sources of biosorbents followed by applications of biosorbents, biosorption isotherms, assessment of biosorbents with various tools, pretreatment of biosorbents, and its mode of action. Some less explored areas like separation of radionuclides, biosorption of volatile organic compounds, and animal-based biosorbents are also explained. Features: Focuses on fundamentals, characteristics of flora and fauna-mediated biosorbents used extensively Describes entire aspects of tools and techniques related to assessment and monitoring of biosorbents Includes adsorption kinetics, adsorption isotherm, and mechanism of action of biosorbents Covers advancements in pretreatment methods to enhance the adsorption process of biosorbents Reviews recent applications which include heavy metal removal, dye remediation, and separation of radionuclides and nano-biosorbents This book is aimed at graduate students and researchers in bioprocess engineering, microbiology, and biotechnology.
