The understanding of how small solid particles operate at liquid interfaces is minimal. This book brings together the topics actively being investigated, with contributions from experts in the field. It will be of interest to researchers in chemistry, physics, chemical engineering, pharmacy, food science and materials science.
Within this volume is a thorough coverage of the fundamental principles embracing modern theories of colloid chemistry applied to mineral processing. It is written in respect for Dr. J.A. Kitchener, distinguished Reader in the Science of Mineral Processing in the Royal School of Mines, Imperial College, University of London (recently retired). Dr. Kitchener's expertise in colloid chemistry has led to numerous fundamental insights and practical advances in flotation, selective flocculation, and the treatment of slimes. Colloid chemistry is inevitably involved in all aspects of mineral processing, ranging from how collectors selectively adsorb on to mineral surfaces in flotation, to the forces which control the stability of dispersions of submicron particles, as well as embracing the behaviour of hydrolyzed metal ions in solid-water slurries. The intelligent use of this information is essential in the effective design of separation processes and strategies by the mineral processor. Up to date bibliographies are included at the end of each of the 13 chapters making this volume a useful general resource for researchers, students and mineral processors.
Colloids are submicron particles that are ubiquitous in both natural and industrial products. Colloids and colloidal systems play a significant role in human health as well as commercial and industrial situations. Colloids have important applications in medicine, sewage disposal, water purification, mining, photography, electroplating, agriculture, and more.This book gathers recent research from experts in the field of colloids and discusses several aspects of colloid morphology, synthesis, and applications. The book is divided into three sections that cover different techniques for the synthesis of colloids, the structure, dynamic and stability of colloids, and applications of colloidal particles, respectively.
Keeping pace with explosive developments in the field, Colloidal Science of Flotation reviews and updates the fundamentals of the bubble-particle collection phenomenon using a self-consistent approach that helps readers understand the hydrodynamic aspects of bubble-particle collection. The authors examine bubble rise velocity, water velocity around air bubbles, the thinning of intervening liquid films, the stability of particle-bubble aggregates, and macroscopic processes in froth. They also survey the applicability of emerging technologies in industrial flotation deinking, wastewater treatment, flotation of plastics, and improvements in minerals and coal flotation.
This new edition of the Handbook of Surface and Colloid Chemistry informs you of significant recent developments in the field. It highlights new applications and provides revised insight on surface and colloid chemistry's growing role in industrial innovations. The contributors to each chapter are internationally recognized experts. Several chapter
Modern Sample Preparation for Chromatography, Second Edition explains the principles of sample preparation for chromatographic analysis. A variety of procedures are applied to make real-world samples amenable for chromatographic analysis and to improve results. This book's authors discuss each procedure's advantages, disadvantages and their applicability to different types of samples, along with their fit for different types of chromatographic analysis. The book contains numerous literature references and examples of sample preparation for different matrices and new sections on green approaches in sample preparation, progress in automation of sample preparation, non-conventional solvents for LLE (ionic liquids, deep eutectic mixtures, and others), and more. - Presents numerous techniques applied for sample preparation for chromatographic analysis - Provides an up-to-date source of information regarding the progress made in sample preparation for chromatography - Describes examples for specific types of matrices, providing a guide for choosing the appropriate sample preparation method for a given analysis

Interactions of Surfactants with Polymers and Proteins covers work done in this area over the last 30 years and examines in detail the physico-chemical, microstructural, and applications aspects of interactions of surfactants with polymers and proteins in bulk surfaces and at interfaces. The physical chemistry of individual components (surfactants, polymers, and proteins) is discussed, and extensive coverage of interactions of surfactants with uncharged, oppositely charged, and hydrophobe modified polymers is provided. Other topics addressed include water soluble and insoluble keratinous proteins, the principles and applications of fluorescence spectroscopy, the physical properties and microstructural aspects of polymer/protein-surfactant complexes, and implications of surfactant interactions with polymers and proteins in practical systems. Interactions of Surfactants with Polymers and Proteins provides a wealth of information for chemists involved in a number of different research areas, including cosmetics, pharmaceutics, foods, paints, pigments, lubrication, ceramics, minerals/materials processing, and biological systems.
The process of froth flotation is an outstanding example of applied surface chemistry. It is extensively used in the mining, mineral, metallurgical, and chemical industries for separation and selective concentration of individual minerals and other solids. Substances so concentrated serve as raw materials for producing appropriate metals and chemicals. The importance of flotation in technology is chiefly due to the ease with which it can be made selective and versatile and to the economy of the process. The objective of this book is to review the fundamentals of surface chemistry together with the relevant aspects of organic and inorganic chemistry that-in the opinion of the author-are important ~ control of the froth flotation process. The review updates the information that had been available in books by Sutherland and Wark (1955), Gaudin (1957), Klassen and Mokrousov (1963), and GIembotsky et al. (1963). It emphasizes mainly the surface chemical aspects of the process, leaving other relevant topics such as hydrodynamics, mechanical and electrical technology, cir cuit design and engineering, operations research, instrumentation tech nology, modeling, etc., to appropriate specialized treatments.
