Book Description
Adsorptive Bubble Separation Techniques focuses on the mechanisms of the various adsorptive bubble separation methods. This book examines the various adsorptive bubble separation techniques, including ion flotation, foam fractionation, precipitate flotation, mineral flotation, bubble fractionation, and solvent sublation. Organized into 20 chapters, this book starts with an overview of the certain important properties of foam. This text then examines the results of several separations, as well as the results of additional studies into the mechanisms of the different techniques. Other chapters explain the studies of foam separation in the case of synthetic solutions, which provide a good knowledge of the extraction mechanisms of the radioactive cations, cesium, cerium, and strontium. This book discusses as well the experimental and theoretical work on foam separation done in Israel. The final chapter deals with the separation of surfactants and metallic ions at various places around the world. This book is a valuable resource for materials scientists, engineers, and chemists.

Book Description
Adsorptive bubble-separation processes are used to remove adsorptive contaminants from wastewater. A mathematical model was developed for the adsorptive bubble separation processes in a countercurrent column. The model included an assumption that linear adsorption of the solute occurred on the gas bubbles. Predictions indicated that aqueous column height has less effect on the solute removal efficiency than water flow rates, gas flow rates or bubble size. Increased water flow rates reduce removal efficiency; greater gas flow rates increase removal efficiency. The maximum removal efficiency is determined by adsorption characteristics of the solute; the removal rate is controlled by mass-transfer rate. However, influent concentrations of the solute in the water phase do not affect removal efficiency. These predictions were tested by means of solvent sublation experiments conducted in a laboratory setting. The data were collected from the sublation of Triton-X100 in a water-ethyl acetate-nitrogen system. Linear regression was used to compare predictions and experimental data with respect to column height. Five column heights ranged from 30 to 100 cm were compared at three water flow rates, 3.0, 5.5 and 13.0 ml/min. The calculated column heights agreed the observed column heights well. As the model predicted, the effect of influent concentraion on the removal efficiency was not significant. The surface excess of Triton-X100 (0.75 E-10 to 7.5 E-10 g mole/cm2) estimated from the adsorption constant in the model agrees with other published values (2.6 E-10 to 2.8 E-10 g mole/cm2). The mass-transfer coefficients of Triton-X100 in water (kL, which ranged from 0.50 to 0.60 cm/min) determined from the model and experimental data at 3.0, 5.5, 8.0 and 13.0 ml/min water flows (Qw) are proportional to the 0.124 power of the water flow rates. kL = 0.0441 Qw0.124 This empirical exponent correlation between mass-transfer coefficients and water flow rates for the adsorption processes is similar to the correlation determined from previous absorption models.

Book Description
Foam fractionation is a separation process in which proteins and other amphipathic species adsorb to the surface of bubbles. The bubbles are then removed from the solution in the form of foam at the top of a column. Due to its cost-effectiveness, foam fractionation has the potential for rapid commercial growth, especially in biotechnology.To assist
