The chapter discusses the strengths and weaknesses of "Comprehensive Analytical Chemistry," a comprehensive reference work in analytical chemistry. While it has started well and sets a high standard, the rapid development of new methods and techniques may make earlier volumes outdated by the time the final volume is published. The book is praised for its fine printing and binding, but the reviewer notes that it faces the challenge of being the first in its field, which may attract mixed reviews. The chapter also reviews two specific books: "Ion Exchange Resins" by Robert Kunin, which is an improved second edition with a strong focus on applications but lacks depth in fundamental aspects, and "A Laboratory Manual on Ion Exchange" by Dr. J. E. Salmon and D. K. Hale, which is a novel approach using a series of experiments to teach ion exchange to students. Finally, the chapter briefly mentions "Researches in Geochemistry," edited by Philip H. Abelson, which provides a valuable overview of current geochemical research in the United States.The chapter discusses the strengths and weaknesses of "Comprehensive Analytical Chemistry," a comprehensive reference work in analytical chemistry.
