Ripu Daman Kumar's book "Activated Carbon From Shells of Walnut Almond Poplar Tree Wood for Phenolics and Heavy Metals Adsorption From Contaminated Water" is a thorough manual on how to make activated carbon out of several materials, including the shells of walnut, almond, and poplar tree wood. The use of activated carbon to remove phenolics and heavy metals from contaminated water is the main topic of this book. The author gives information on the physical and chemical characteristics of the materials used in the manufacturing of activated carbon as well as a description of the process itself. The adsorption of phenolics and heavy metals from contaminated water using activated carbon is covered in great length in the book. It addresses a variety of subjects, including the carbon's capacity for adsorption, the impact of various parameters on the adsorption process, and the application of activated carbon in the treatment of water. For those working in the fields of environmental science, water treatment, and chemical engineering, this book is an invaluable resource. This book is a thorough reference for anyone interested in the production and use of activated carbon in the removal of impurities from water due to the exhaustive description of the processes involved in both its manufacturing and its usage in water treatment. For individuals who are interested in the creation and application of efficient techniques for the treatment of polluted water, "Activated Carbon From Shells of Walnut Almond Poplar Tree Wood for Phenolics and Heavy Metals Adsorption From Contaminated Water" is a must-read.
