The study concluded that the Jones-Ray effect may not originate from salts, as it becomes nonobservable when the surface excess of impurities is lessened by ultrafine gas bubbles in salt solutions.
The cause of the Jones-Ray effect has been controversially debated for years. Ultrafine gas bubbles were employed to lessen the surface excess of the surface-active impurities adsorbing to the air/water interface of the salt solutions, which would lead to a direct shift in surface tension observable by the Wilhelmy plate method. It was concluded in this study that once the surface excess of the inevitable impurities in the salts is lessened by the introduction of ultrafine gas bubbles, which possess great air/water interfacial area, the Jones-Ray effect becomes nonobservable. Therefore, our finding hypothesized that the Jones-Ray effect might not originate from salts.
