Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: 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 excerpt: 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

Book excerpt: This present work emphasized on the current knowledge regarding (i) feasibility of multi–stage forth flotation operation for oil removal, and (ii) comprehension of dynamic surface tensions of surfactant solutions in relation to foam characteristics. A multi–stage forth flotation efficiency depends on the enhancement of interfacial adsorption and the number of bubble caps and tray. The operational parameters including foam height, air flow rate and feed flow rate were controlled to obtain the optimum process performance. Under the optimum conditions—a number of trays of 4, a foam height of 60 cm, an air flow rate of 40 L/min, a feed flow rate of 60 mL/min, a surfactant concentration of 0.3% (w/v), and an NaCl concentration of 1.5% (w/v)—the enrichment ratio and the removal of motor oil could reach as high as 16.3 and 97.9%, respectively. Furthermore, the effects of surfactant structure on the equilibrium and dynamic surface tension were investigated and discussed to correlate with foam properties. For all studied surfactant solutions, the equilibrium experimental data were well fitted with the Langmuir adsorption isotherm, while the dynamic surface tension data were used to calculate diffusivity values of all studied surfactants by using Word-Tordai equation. It was found that a surfactant having longer alkyl group has a lower diffusivity value, whereas a surfactant having larger head group size has a higher diffusivity. The adsorption process of surfactant onto the air/water interface of generated bubbles was controlled by the diffusion.

Book excerpt: In this research, foam fractionation a method belonging to the Adsorptive Bubble Separation Methods, was employed to enrich the following active principles contained in medically valuable plants: Faradiol esters from Calendula officinalis, catechins from Camellia sinensis, tryptanthrin from Isatis Tinctoria and cannabinoids from Cannabis sativa. The enrichment methods have been developed in the batch mode for these principles aqueous dilute solutions, based on their physicochemical nature and the process parameters and conditions. The hydrophobicity of faradiol esters, tryptanthrin, cannabinoids and catechins complexes with caffeine, permitted their enrichments. Optimisation was achieved for foam fractionation columns with high residence times, the utilisation of additives and by adjusting the solutions pH values.
