Analysis of Noble Metals: Overview and Selected Methods describes simple techniques with useful sensitivity, accuracy, and precision for noble metal analysis. This book is composed of seven chapters that include the methods of atomic absorption, spectrochemical, spectrophotometric, gravimetric, volumetric, and potentiometric determinations of noble metals. Each chapter discusses the concept, principles, practice, and application of the specific analytical technique. A chapter examines several separation methods for noble metals, including cation exchange, mercury amalgam, reduction, silver assay beads, solvent extraction, and dissolution. This book will be of great value to analytical chemists, instrumental engineers, and researchers.
