In order to investigate the behavior and mechanism of spherical plastic particles attaching to the bubble surface, observations were made in a model system in which spherical plastic particles were dropped onto a stationary air bubble formed in water within a glass cell. Their interaction was recorded by high-speed digital video. The image processing method was used to extract the particle trajectories, the relationship between the collision angle and the movement time. The influence of the collision position of the particles and the diameter of bubble and particles on their adhesion behavior was studied. The experimental results show that the attachment of particles is mainly divided into collision attachment and sliding attachment. The mobile surface assumption of the bubble surface agrees very well with the experimental value. In addition, through the statistics of multiple experimental data, it is found that with the increase of the collision angle, the induction time increases significantly, but the time for the particles to fall into the bubble surface is maintained at 10 ms. The depth of the particles trapped in the bubble is affected by both the bubble and the particle size, accounting for about 2% of the sum of bubble diameter and particle diameter.
