The capture of solid particles suspended in aqueous solution by rising gas bubbles involves hydrodynamic and physicochemical processes that are central to colloid science. Of the collision, attachment and aggregate stability aspects to the bubble-particle interaction, the crucial attachment process is least understood. This is especially true of hydrophilic solids. We review the current literature regarding each component of the bubble-particle attachment process, from the free-rise of a small, clean single bubble, to the collision, film drainage and interactions which dominate the attachment rate. There is a particular focus on recent studies which employ single, very small bubbles as analysis probes, enabling the dynamic bubble-hydrophilic particle interaction to be investigated, avoiding complications which arise from fluid inertia, deformation of the liquid-vapour interface and the possibility of surfactant contamination.

小气泡和亲水性固体相遇的动态方面。

通过上升的气泡捕获悬浮在水溶液中的固体颗粒涉及胶体科学至关重要的流体动力学和物理化学过程。在气泡-颗粒相互作用的碰撞，附着和聚集体稳定性方面，至关重要的附着过程了解最少。对于亲水性固体尤其如此。我们回顾了有关气泡-颗粒附着过程各个组成部分的当前文献，从小而干净的单个气泡的自由上升到碰撞，薄膜排水以及决定附着率的相互作用。特别关注最近的研究，该研究使用单个很小的气泡作为分析探针，从而能够研究动态气泡-亲水颗粒之间的相互作用，避免了因流体惯性而引起的复杂情况，
