The Analytical Chemistry of the Noble Metals

Analytical Chemistry, Volume 24: The Analytical Chemistry of the Noble Metals describes the procedures for the separation, extraction, and analysis of noble metals.
This book is composed of seven chapters, and begins with a survey on the influence of metallurgical factors on the susceptibility of platinum and gold metals to various corrosive agents. The succeeding chapter provides the methods of isolation of osmium and ruthenium from associated platinum metals and from base metals. A chapter examines the application of gravimetric methods for the separation of seven noble metals, including ruthenium, osmium, rhodium, iridium, palladium, platinum, and gold. Other chapters consider the procedures for volumetric, spectrophotometric, and spectrochemical analysis of noble metals. The concluding chapter describes the features and attributes of the equipment for noble metal analysis. This book is of value to analytical chemists and workers and researchers in metallurgy.
