“…It is seen from the gure that the microbubble dispersion shows a S-shaped curve. The S-shaped curve is also reported in previous studies for microbubble dispersion (Feng et al, 2009;Ruby and Majumder, 2018;Yan et al, 2005). It is seen from the Fig.…”

“…The addition of glycerol also reduces the microbubble dispersion (Parmar and Majumder, 2015). Ruby and Majumder (2018) also reported the reduction in size of microbubble with SDS and Saponin. The addition of surfactant also imparts an additional shear on trailing pole of the bubble due to concentration gradient.…”

“…Amiri and Sadeghialiabadi (2014) further evaluate the stability of microbubble in the presence of montmorillonite nanoparticles. Recently Ruby and Majumder (2018) examined the stability of micro and nano-particle loaded microbubbles. Unfortunately, there is a cognition gap on various properties of microbubble dispersion which are important for implication of microbubbles to large scale.…”

Microbubbles are small gas filled bubbles which has wide application in various industries. Stability of microbubble dispersion is of primary concern for the application of microbubbles in these fields. In this research, the stability of microbubble dispersion generated using CTAB surfactant is analysed by drainage mechanism. The stability is studied on the basis of half-life of microbubble dispersion. Microbubble dispersion gas fraction and rise velocity of microbubble is also calculated and the size of microbubble is estimated from the rise velocity of microbubble. Further, Silica nanoparticles are added in the surfactants to study their effect on the stability of microbubble dispersion. The observed results clearly indicates that the stability of microbubble dispersion is significantly affected by the surfactant concentration and the weight of silica nanoparticle in the liquid. Similar results were observed for rise velocity and bubble size. The present work may be beneficial for the application of microbubble in various chemical and biochemical industries and scientific community.

“…Several methods were designed to study the stability and gas holdup of the ionic microbubbles. The gas holdup was estimated by phase isolation method . The method proposed by Amiri and Woodburn was used to determine the size of bubbles based on the increased velocity of bubbles as a function of gas holdup.…”

This work presents the study of the stability of microbubbles based on the assemblage at air−water and liquid−solid interfaces with prominence on the systems containing surface-active agents and micro-or nanoparticles. Sodium chloride, lithium chloride, and cesium chloride salts in the presence of sodium dodecyl sulfate (an anionic surface-active agent) are efficient in decreasing the interfacial tension of air−water. For systems involving salt−water interfaces, the addition of salt effectively lowers the surface tension by reducing the critical micelle concentration (cmc) of the surface-active agent. The present observation shows the maximum decrease in the cmc with the addition of salt obtained in the order: CsCl > LiCl > NaCl. The insertion of negatively charged hydrophilic copper oxide nanoparticles (size < 50 nm, transmission electron microscopy) increases the efficacy of the microbubbles formulated with ionic surface-active molecules. This efficacy is due to the repulsive Coulomb interactions at the interfaces, which cause the adsorption at the interfaces. The stability of microbubbles increased with the increase in the concentration of salt in the case of CsCl, while it decreased for NaCl, and a mixed effect was observed with LiCl.
