The field of applied chemistry deals with the application of theories and principles of chemistry to practical problems. It also seeks to understand the basic chemical properties of materials and developing new materials with well-controlled functions. Some of the major specializations in the field of applied chemistry include analytical chemistry, materials design, environmental technology and bioscience. Analytical chemistry makes use of methods and instruments for the purpose of identifying, separating and quantifying matter. It comprises modern instrumental methods and classical wet chemical methods. Environmental technology involves the application of scientific knowledge and engineering to solve environmental problems and address sustainability. This book contains comprehensive coverage of different concepts related to the field of applied chemistry. It is an essential guide for both academicians and those who wish to pursue this discipline further. Coherent flow of topics, student-friendly language and extensive use of examples make this book an invaluable source of knowledge.
