"Biomass and Activated Carbon Dye Adsorption"

"Biomass and Activated Carbon Dye Adsorption" by R. Bhuvaneswari is a comprehensive book that delves into the latest research and developments in the field of adsorption of dyes using biomass and activated carbon. The book covers various aspects of adsorption, including adsorbents, adsorption kinetics, isotherms, equilibrium, surface chemistry, and physical and chemical adsorption. It discusses the different types of pores such as micropores, mesopores, and macropores, and their significance in adsorption. The book also examines the surface area and functional groups of adsorbents, and how they affect adsorption capacity.

The author explains the various techniques involved in the production of activated carbon from biomass, such as biomass pyrolysis, carbonization, and activation using different activating agents, activation temperatures, and activation time. The book also discusses the factors affecting adsorption capacity, such as pH, temperature, and concentration, and the methods of regeneration of used adsorbents.

The book focuses on the application of biomass and activated carbon for wastewater treatment, specifically for the removal of textile dyes such as reactive dyes, azo dyes, direct dyes, acid dyes, basic dyes, and disperse dyes. The author describes the different adsorption mechanisms such as intraparticle diffusion, external mass transfer, film diffusion, and pore diffusion, and their role in the adsorption process.

The book also covers the various interactions involved in adsorption, such as electrostatic interaction, hydrogen bonding, and π-π stacking, and the concept of competitive adsorption. The author explains the thermodynamics of adsorption, including entropy, enthalpy, and free energy.

Overall, this book is a valuable resource for researchers, academics, and professionals in the field of environmental science and engineering who are interested in the application of biomass and activated carbon for the removal of textile dyes from wastewater. It provides a comprehensive understanding of the adsorption process and the factors affecting adsorption, as well as the methods of production and modification of adsorbents.
