Study of Ultrafine Bubble Stabilization by Organic Material Adhesion

We confirmed the effect of organic material adhesion as ultrafine bubble(UFB) stabilization mechanism. Organic material was added to generate UFB,and the state of UFB particles was investigated by dynamic light scattering method, transmission electron microscope (TEM), resonance mass measurement method. Disappearance of UFB was suppressed by the addition of organic material, and it was confirmed that the organic material adhered to the surface of UFB. We got the conclusion that adhesion of organic material inhibit gas dissolution from bubbles.
