Quantitative Chemical Analysis

By: Na Li,John J Hefferren,Ke'an Li

This book covers both fundamental and practical aspects of chemical analysis: Data Process and Analysis; Chemical Equilibria and Volumetric titrations; Gravimetry; Spectrophotometry; Sample Preparation and Separation Methods in Quantitative Analysis. It was written with the rich tradition of teaching at Peking University College of Chemistry, and edited by an American professor who was personally sensitive to the needs of students learning science from traditional chemistry textbooks written in English. Many examples and illustrative problems in this text have been taken from previous textbooks by the Peking University Team Teaching Program. The book can be used as a starter in analytical chemistry which is fundamental and the base upon which chemistry is built. Traditional chapters of initial learning in analytical chemistry are included, such as volumetric, gravimetric and separation methods; the book also includes key chapters on problem solving relating to recent progress in analytical chemistry.

UV-A

Biological Effects of Ultraviolet Radiation with Emphasis on Human Responses to Longwave Ultraviolet

By: John Parrish

The origin of this text was a request by industry and government to summarize the biological effects and to estimate the limits of safe exposure to longwave ul traviolet radiation. The specific issue was the safety of a small medium-pressure mercury arc designed to emit UV-A (NUVA-Lite, L. D. Caulk Co. , Milford, Delaware) for photopolymerization of resinous fillings used in dentistry. How- ever, the context grew to become a consideration of the risks and benefits to hu mans of electromagnetic radiation between the biologically active short UV and the visible spectrum. We have accumulated data from our own experimental work and from the literature and have attempted to put this information in the perspective of known biologic effects of ultraviolet radiation as it influences hu mans. Interest in the biological effects of longwave ultraviolet radiation is increas ing in all of the many scientific disciplines that make up the complex field of photobiology. In order to minimize the chance for error and personal prejudice and to maximize the use of expertise, each chapter has been reviewed by several authorities. Some of the contributions of this group led to significant alterations and creative additions to the chapter, and these persons deserve not only our sin cere gratitude but also recognition by the reader. These include Chapters 2 and 3: Dr. Robert E. Levin, Mr. Charles P. Comeau, Mr. Donald Gonser, Dr. David Sliney; Chapter 5: Dr. Jerry Williams, Dr. Robert Webb, Dr. Madhu A.
