Biosorption technique is followed utilizing cost effective and highly efficient biosorbent i.e. sugarcane bagasse for the treatment of wastewater contaminated with vinyl sulfone reactive blue 21 dye. Adsorption capacity of sugarcane bagasse is enhanced by chemical pretreatment with hydrochloric acid. Optimization of adsorption parameters is carried out resulting in more than 90% dye removal.

Biosorption has been recognized as an effective method of reduction of fluoride contamination in surface water and aqueous solutions. Biosorption can be defined as the removal of fluorides, metals, compounds and particulates from solution by biological material. Biosorption of fluorides from aqueous solutions is a relatively new technology for the treatment of wastewater. In the present study, the fluoride removal potential of calcium alginate (CA), chitosan coated calcium alginate (CCCA), chitosan coated perlite (CCP), chitosan coated silica (CCS), perchloric acid cross linked calcium alginate (PCA) and glutaraldehyde cross linked calcium alginate (GCA) beads is investigated by both batch and column studies. Further the biosorbents are characterized by FTIR, SEM, TGA, XRD, porosity and surface analysis to understand the mode of fluoride-biomass interaction. The basic objective of the study is to contribute to the understanding and modeling of the equilibrium adsorption process.

Azo Dye Biodegradation by Immobilized Yeast
41,10 € *

Textile industries use large amounts of water and a wide variety of synthetic dyes. A small concentration of these dyes released in the environment can be extremely toxic in aquatic ecosystems. Among dye removal processes, adsorption, biosorption and biodegradation are the most advantageous techniques. In order to increase the efficiency of these processes, cell immobilization allows that metabolic processes can take place in adverse conditions. Therefore, this study aims the use of Saccharomyces cerevisiae immobilized in activated sugarcane bagasse to promote Acid Black 48 dye (AB48) biodegradation and biosorption in aqueous solutions. Our results indicate that use of immobilized yeast for decoloration and biodegradation is very promising. Peaks detected in FT-IR spectra suggest probable changes in the dye molecule and the formation of new metabolites. In addition to high dye removal and degradation rates, immobilized yeast cells can also be easily precipitated and removed when compared to the use of free cells.

This is the first volume on adsorption using green adsorbents and is written by international contributors who are the leading experts in the adsorption field. The first volume provides an overview of fundamentals and design of adsorption processes. For people who are new to the field, the book starts by two overview chapters presenting the principles and properties of wastewater treatment and adsorption processes. The book also provides a comprehensive source of knowledge on acid-base properties of biosorbents. It discusses fractal-like kinetic models for fluid-solid adsorption, reports on the chemical characterization of oxidized activated carbons for metal removal, and the use of magnetic biosorbents in water treatment.Furthermore, the thermodynamic properties of metals adsorption by green adsorbents, and biosorption of polycyclic aromatic hydrocarbons and organic pollutants are reviewed, and finally the recent trends and impact of nanomaterials as green adsorbent and potential catalysts for environmental applications are summarized.The audience for this book includes students, environmentalists, engineers, water scientists, civil and industrial personnel who wish to specialize in adsorption technology. Academically, this book will be of use to students in chemical and environmental engineering who wish to learn about adsorption and its fundamentals. It has also been compiled for practicing engineers who wish to know about recent developments on adsorbent materials in order to promote further research toward improving and developing newer adsorbents and processes for the efficient removal of pollutants from industrial effluents. It is hoped that the book will serve as a readable and useful presentation not only for undergraduate and postgraduate students but also for the water scientists and engineers and as a convenient reference handbook in the form of numerous recent examples and appended information.
